which will put a PostgreSQL database into an unusable state. pg_amcheck, If you are on PostgreSQL 14, you will be affected by the 9 Fix ALTER MATERIALIZED VIEW RENAME COLUMN to return a more appropriate command tag. The trigger_file setting has been renamed to promote_trigger_file. PostgreSQL 11: November 9, 2023. The fix for CVE-2022-1552 Allow ALTER TABLE SET NOT NULL to avoid unnecessary table scans (Sergei Kornilov). bug reports of index corruption in PostgreSQL 14 and shortly after the PostgreSQL 14.3 On May 12, 2022, the PostgreSQL Global Development Group Allow discovery of an LDAP server using DNS SRV records (Thomas Munro). By submitting my information I agree that Percona may use my personal data in sending communication to me about Percona services. Pandoc produces better output than lynx and avoids some locale/encoding issues. Note that if you are on PostgreSQL 14, you Improve speed of btree index insertions by reducing locking overhead (Alexander Korotkov), Support INCLUDE columns in GiST indexes (Andrey Borodin), Add support for nearest-neighbor (KNN) searches of SP-GiST indexes (Nikita Glukhov, Alexander Korotkov, Vlad Sterzhanov), Reduce the WAL write overhead of GiST, GIN, and SP-GiST index creation (Anastasia Lubennikova, Andrey V. Lepikhov), Allow index-only scans to be more efficient on indexes with many columns (Konstantin Knizhnik), Improve the performance of vacuum scans of GiST indexes (Andrey Borodin, Konstantin Kuznetsov, Heikki Linnakangas), Delete empty leaf pages during GiST VACUUM (Andrey Borodin), Reduce locking requirements for index renaming (Peter Eisentraut), Allow CREATE STATISTICS to create most-common-value statistics for multiple columns (Tomas Vondra). Aside from many bug, performance and security fixes these are some relevant news from PostgreSQL 11 that might help DEV: This is huge! Major enhancements in PostgreSQL 12 include: General performance improvements, including: Optimizations to space utilization and read/write performance for B-tree indexes, Partitioning performance enhancements, including improved query performance on tables with thousands of partitions, improved insertion performance with INSERT and COPY, and the ability to execute ALTER TABLE ATTACH PARTITION without blocking queries, Automatic (but overridable) inlining of common table expressions (CTEs), Reduction of WAL overhead for creation of GiST, GIN, and SP-GiST indexes, Support for covering GiST indexes, via the INCLUDE clause, Multi-column most-common-value (MCV) statistics can be defined via CREATE STATISTICS, to support better plans for queries that test several non-uniformly-distributed columns. specifically with the --heapallindexed flag. The walsender process starts logical decoding of the WAL and loads the standard logical decoding plugin. Include the application_name, if set, in log_connections log messages (Don Seiler), Make the walreceiver set its application name to the cluster name, if set (Peter Eisentraut), Add the timestamp of the last received standby message to pg_stat_replication (Lim Myungkyu), Add a wait event for fsync of WAL segments (Konstantin Knizhnik), Add GSSAPI encryption support (Robbie Harwood, Stephen Frost). printf-family functions, as well as strerror and strerror_r, now behave uniformly across platforms within Postgres code (Tom Lane). Add REINDEX CONCURRENTLY option to allow reindexing without locking out writes (Michal Paquier, Andreas Karlsson, Peter Eisentraut). Previously, CTEs were never inlined and were always evaluated before the rest of the query. Adjust to_timestamp()/to_date() functions to be more forgiving of template mismatches (Artur Zakirov, Alexander Korotkov, Liudmila Mantrova). Add planner support function interfaces to improve optimizer estimates, inlining, and indexing for functions (Tom Lane). This new behavior more closely matches the Oracle functions of the same name. Previously, this happened by default if no destination was specified, but that was deemed to be unfriendly. take this update. safe to take the upgrade, you should do so. At the end of the migration, you can delete the subscription in your new primary node in PostgreSQL 12: Before using the logical replication, please keep in mind the following limitations: Keeping your PostgreSQL server up to date by performing regular upgrades has been a necessary but difficult task until PostgreSQL 10 version. Allow pg_upgrade to use the file system's cloning feature, if there is one (Peter Eisentraut). Restrict visibility of rows in pg_stat_ssl for unprivileged users (Peter Eisentraut), At server start, emit a log message including the server version number (Christoph Berg), Prevent logging incomplete startup packet if a new connection is immediately closed (Tom Lane). This site is protected by reCAPTCHA and the Google At the end of a development cycle, the OIDs used by committed patches will be renumbered down to lower numbers, currently somewhere in the 4xxx range, using the new renumber_oids.pl script. The following example should produce true in both cases, but it produces false in case of *{2}. Since it requires downtime it should be carefully planned and notified. While upgrading to 14.3 et al. Since PostgreSQL 10, it has implemented built-in logical replication which, in contrast with physical replication, you can replicate between different major versions of PostgreSQL.
