Allow ALTER TABLE ... SET NOT NULL to avoid unnecessary table scans (Sergei Kornilov). The project continues to receive recognition across the industry, Use of these options reduces VACUUM's locking requirements, but prevents returning disk space to the operating system. Rename command-line tool pg_verify_checksums to pg_checksums (Michaël Paquier), In pg_restore, require specification of -f - to send the dump contents to standard output (Euler Taveira). Version 12 contains a number of changes that may affect compatibility with previous releases. MAJOR – Starting with PostgreSQL 10, each new major release increases a part of the MAJOR version … The In previous releases, using an incorrect integer value for connection parameters connect_timeout, keepalives, keepalives_count, keepalives_idle, keepalives_interval and port resulted in libpq either ignoring those values or failing with incorrect error messages. Previously, this happened by default if no destination was specified, but that was deemed to be unfriendly. Add --exclude-database option to pg_dumpall (Andrew Dunstan), Add CREATE ACCESS METHOD command to create new table types (Andres Freund, Haribabu Kommi, Álvaro Herrera, Alexander Korotkov, Dmitry Dolgov). In this release, a WITH Specifically, dynamic_shared_memory_type can no longer be set to none. Note however that inequality restrictions, for example. Add REINDEX CONCURRENTLY option to allow reindexing without locking out writes (Michaël Paquier, Andreas Karlsson, Peter Eisentraut). A strong random-number source is now required. Just-in-time (JIT) compilation using LLVM, introduced in PostgreSQL 11, is now enabled by default. Previously, this operation was only possible by using pg_ctl or creating a trigger file. This allows this parameter to be set by postgres_fdw. of the world's most advanced open source database. define "nondeterministic collations" Add ability to enable/disable cluster checksums using pg_checksums (Michael Banck, Michaël Paquier). Support functions can also supply simplified representations and index conditions, greatly expanding optimization possibilities. This release also Latest News PostgreSQL 13.1, 12.5, 11.10, 10.15, 9.6.20, & 9.5.24 Released!! Improve optimization of partition and UNION ALL queries that have only a single child (David Rowley), Improve processing of domains that have no check constraints (Tom Lane). Previously, displayed floating-point values were rounded to 6 (for real) or 15 (for double precision) digits by default, adjusted by the value of extra_float_digits. The PostgreSQL Global Development Group today announced the release of PostgreSQL 12, the latest version of the world's most advanced open source database. This server should have a non-root user with administrative privileges and a firewall configured with firewalld. PostgreSQL 12 provides significant performance and maintenance enhancements to The system catalogs that previously had hidden oid columns now have ordinary oid columns. The new function pg_partition_root() returns the top-most parent of a partition tree, pg_partition_ancestors() reports all ancestors of a partition, and pg_partition_tree() displays information about partitions. retrieve data from a limited subset. Cause PostgreSQL Version 12 is not currently supported with Tableau … Build Cygwin binaries using dynamic instead of static libraries (Marco Atzeri), Remove configure switch --disable-strong-random (Michaël Paquier). Do not pretty-print the result of xpath() or the XMLTABLE construct (Tom Lane). Mark table columns of type name as having “C” collation by default (Tom Lane, Daniel Vérité), The comparison operators for data type name can now use any collation, rather than always using “C” collation. Allow pg_stat_statements_reset() to be more granular (Haribabu Kommi, Amit Kapila). Without much wait, let’s buckle to the installation of PostgreSQL 12 on Ubuntu 20.04… For example, allow a variable called comment to exist in a function that calls the COMMENT SQL command. Domains that are being used purely as type aliases no longer cause optimization difficulties. path expression support, optimizations for how common table expression PostgreSQL releases are versioned using the following scheme: MAJOR.MINOR. it easier to manage database workloads large and small while building on For releases before PostgreSQL version 10.0, version numbers consist of three numbers, for example, 9.5.3. PostgreSQL 12 introduces "generated columns." Allow control of the auto_explain log level (Tom Dunstan, Andrew Dunstan), Update unaccent rules with new punctuation and symbols (Hugh Ranalli, Michaël Paquier), Allow unaccent to handle some accents encoded as combining characters (Hugh Ranalli), Allow unaccent to remove accents from Greek characters (Tasos Maschalidis), Add a parameter to amcheck's bt_index_parent_check() function to check each index tuple from the root of the tree (Peter Geoghegan), Improve oid2name and vacuumlo option handling to match other commands (Tatsuro Yamada). This output can also be obtained when using auto_explain by setting auto_explain.log_settings. Add colorization to the output of command-line utilities (Peter Eisentraut). This means that a REINDEX operation on an index pg_upgrade'd from a previous release could potentially fail. Continue to use PostgreSQL Version 11 or lower if possible. Queries on partitioned tables have also seen demonstrable improvements, This feature allows TCP/IP connections to be encrypted when using GSSAPI authentication, without having to set up a separate encryption facility such as SSL. please use This change adds a VACUUM command option INDEX_CLEANUP as well as a table storage option vacuum_index_cleanup. Specifically, CTEs are automatically inlined if they have no side-effects, are not recursive, and are referenced only once in the query. this form Add progress reporting to pg_checksums (Michael Banck, Bernd Helmle). create their own methods for storing data. This new check is enabled with clientcert=verify-full. PostgreSQL 13 13.1 13.0 PostgreSQL 12 ... 12.1 12.0 PostgreSQL 11 11.10 11.9 11.8 11.7 11.6 11.5 11.4 11.3 available if your PostgreSQL installation is compiled or packaged with LLVM. "This release continues the trend of making Use pread() and pwrite() for random I/O (Oskari Saarenmaa, Thomas Munro). This allows ECPG clients to interact with bytea data directly, rather than using an encoded form. by DB-Engines and receiving the In support of this, add hostgssenc and hostnogssenc record types in pg_hba.conf for selecting connections that do or do not use GSSAPI encryption, corresponding to the existing hostssl and hostnossl record types. Allow vacuumdb to disable waiting for locks or skipping all-visible pages (Nathan Bossart). While CHECK OPTIONs on postgres_fdw tables are ignored (because the reference is foreign), views on such tables are considered local, so this change enforces CHECK OPTIONs on them. Notably, cases involving NaN, underflow, overflow, and division by zero are handled more consistently than before. release provides application developers with new capabilities such as SQL/JSON Specifically, in XMLTABLE, xpath(), and xmlexists(), fix some cases where nothing was output for a node, or an unexpected error was thrown, or necessary escaping of XML special characters was omitted. Indexes pg_upgrade'd from previous releases will not have these benefits. Copyright © 1996-2020 The PostgreSQL Global Development Group, PostgreSQL 13.1, 12.5, 11.10, 10.15, 9.6.20, & 9.5.24 Released. This affects only the INSTALL file generated during make dist and the seldom-used plain-text postgres.txt output file. Improve speed in converting strings to int2 or int4 integers (Andres Freund), Allow parallelized queries when in SERIALIZABLE isolation mode (Thomas Munro). Enhancements to administrative functionality, including: REINDEX CONCURRENTLY can rebuild an index without blocking writes to its table, pg_checksums can enable/disable page checksums (used for detecting data corruption) in an offline cluster, Progress reporting statistics for CREATE INDEX, REINDEX, CLUSTER, VACUUM FULL, and pg_checksums, Nondeterministic ICU collations, enabling case-insensitive and accent-insensitive grouping and ordering, Encryption of TCP/IP connections when using GSSAPI authentication, Discovery of LDAP servers using DNS SRV records, Multi-factor authentication, using the clientcert=verify-full option combined with an additional authentication method in pg_hba.conf. PostgreSQL expands on its robust authentication method support with several PostgreSQL is a powerful, open source object-relational database system. Add OR REPLACE option to CREATE AGGREGATE (Andrew Gierth), Allow modifications of system catalogs' options using ALTER TABLE (Peter Eisentraut), Modifications of catalogs' reloptions and autovacuum settings are now supported. several features to continue its implementation of the SQL standard with Progress is reported in the pg_stat_progress_cluster system view. Pandoc version 1.13 or later is required. Include partitioned indexes in the system view pg_indexes (Suraj Kharage), Add psql command \dP to list partitioned tables and indexes (Pavel Stehule), Improve psql \d and \z display of partitioned tables (Pavel Stehule, Michaël Paquier, Álvaro Herrera), Fix bugs that could cause ALTER TABLE DETACH PARTITION to leave behind incorrect dependency state, allowing subsequent operations to misbehave, for example by not dropping a former partition child index when its table is dropped (Tom Lane), Improve performance and space utilization of btree indexes with many duplicates (Peter Geoghegan, Heikki Linnakangas). Initialize and start database service. method (e.g. Observe the following incompatibilities: Remove the special behavior of oid columns (Andres Freund, John Naylor). Inlining can be prevented by specifying MATERIALIZED, or forced for multiply-referenced CTEs by specifying NOT MATERIALIZED. The functions for this are pg_copy_physical_replication_slot() and pg_copy_logical_replication_slot(). Allow foreign keys to reference partitioned tables (Álvaro Herrera), Improve speed of COPY into partitioned tables (David Rowley), Allow partition bounds to be any expression (Kyotaro Horiguchi, Tom Lane, Amit Langote). database systems, but exceeds them in advanced database features, extensibility, Such expressions are evaluated at partitioned-table creation time. Do not allow multiple conflicting recovery_target* specifications (Peter Eisentraut). PostgreSQL, with further additions to internationalization, authentication, sudo vim /etc/postgresql/13/main/postgresql.conf # ...and change "port = 5433" to "port = 5432" sudo vim /etc/postgresql/12/main/postgresql.conf # ...and change "port = 5432" to "port … This avoids conflict failures during restore. While there is no specific policy reserving any OIDs for external use, it is recommended that forks and other projects needing private manually-assigned OIDs use numbers in the high 7xxx range. PostgreSQL 12 includes better management of indexing, improved partitioning capabilities, JSON path queries per SQL/JSON … Let’s start mentioning some of the most important features and improvements of this new PostgreSQL version. The function now allows reset of statistics for specific databases, users, and queries. This provides a simple way to filter incoming data. Use of this option reduces the ability to reclaim space and can lead to index bloat, but it is helpful when the main goal is to freeze old tuples. The new checks allow for run-time validation of INTO column counts and single-row results. it was renamed from "POSTGRES" to "PostgreSQL" - and PostgreSQL 12 adds contents of other columns in the same table. This will avoid conflicts with recently-merged patches, and it should be a long time before the core project reaches that range. Speed up keyword lookup (John Naylor, Joerg Sonnenberger, Tom Lane), Improve search performance for multi-byte characters in position() and related functions (Heikki Linnakangas), Allow toasted values to be minimally decompressed (Paul Ramsey). Additionally, PostgreSQL 12 can now enable or disable page checksums in an particularly over larger data sets, and overall space utilization. Allow the streaming replication timeout (wal_sender_timeout) to be set per connection (Takayuki Tsunakawa). Remove obsolete pg_constraint.consrc column (Peter Eisentraut). offline cluster using the pg_checksums The specific colors used can be adjusted by setting the environment variable PG_COLORS, using ANSI escape codes for colors. recovery.conf is no longer used, and the server will not start if that file exists. For example, in PostgreSQL 12.1, 12 is a major version, and 1 is a minor version. B-tree Indexes, the standard type of indexing in PostgreSQL, have been There are additional enhancements to indexing in PostgreSQL 12 that affect PostgreSQL is known for its conformance to the SQL standard - one reason why This allows cross-type comparisons to be processed more efficiently. COPY, and includes the Previously, ALTER TYPE ... ADD VALUE could not be called in a transaction block, unless it was part of the same transaction that created the enumerated type. command. Before PostgreSQL 10, a major version was indicated by increasing either the first or second … The function, pg_ls_tmpdir(), optionally allows specification of a tablespace. Previously, it defaulted to current. Below is the complete archive of release notes for every version of PostgreSQL. This allows pg_restore to perform more-fully-parallelized parallel restores, especially in cases where the original dump was not done in parallel. Page, a core team member of the Previously, multiple different instances of these parameters could be specified, and the last one was honored. Internal pages and min/max leaf page indicators now only store index keys until the change key, rather than all indexed keys. Simplify renumbering manually-assigned OIDs, and establish a new project policy for management of such OIDs (John Naylor, Tom Lane). Swap the ports for the old and new PostgreSQL versions. The best way to install PostgreSQL 12 on Ubuntu 18.04 is to use the repository that PostgreSQL … More easily than before PostgreSQL version 12 contains a number of system V shared memory ( Kyotaro ).
