it into your production environment. latest available minor release available for a major version. pg_amcheck, Previously returned true, if ESCAPE NULL is specified. This reduces the number of system calls required for I/O. Allow time-based server parameters to use units of microseconds ( us) (Tom Lane) Allow fractional input for integer server parameters (Tom Lane) For example, SET work_mem = '30.1GB' is now allowed, even though work_mem is an integer parameter. This feature supports nondeterministic collations that can define case- and accent-agnostic equality comparisons. Improve speed in converting strings to int2 or int4 integers (Andres Freund), Allow parallelized queries when in SERIALIZABLE isolation mode (Thomas Munro). To accomplish upgrades you needed to think of other ways of upgrading, such as using pg_upgrade, dumping and restoring, or using some third party tools like Slony or Bucardo, all of them having their own caveats. Avoiding file recycling can be beneficial on copy-on-write file systems like ZFS. "C:\Program Files\PostgreSQL \12" is the default installation directory for the 12.x version. Previously, the database's default collation was used for all statistics. This allows pg_restore to perform more-fully-parallelized parallel restores, especially in cases where the original dump was not done in parallel. We will create pub1 publication in the publisher node, for all the tables: The user that will create a publication must have the CREATE privilege in the database, but to create a publication that publishes all tables automatically, the user must be a superuser. Useful in case of related data that's queried all the time with the indexed column(s). This allows this parameter to be set by postgres_fdw. Luckily now it is a different story thanks to logical replication. Sequence data is not replicated. Add EXPLAIN option SETTINGS to output non-default optimizer settings (Tomas Vondra). On the subscriber side, it also requires the max_replication_slots to be set. This will take an In PostgreSQL, the underlying catalog columns are really of type name. I've used PostgreSQL for many years and I've always found it extremely stable, I've also been using DEV locally with PostgreSQL 11 since its release in October 2018 without any issue. The fix for CVE-2022-1552 is much easier This is controlled by the --no-sync option. reproduce the issue. an essential part of PostgreSQL maintenance Add REINDEX CONCURRENTLY option to allow reindexing without locking out writes (Michal Paquier, Andreas Karlsson, Peter Eisentraut). This can be optimized when the table's column constraints can be recognized as disallowing nulls. If it is not required, then you can uninstall the older PostgreSQL. As the schema is not replicated, you must take a backup in PostgreSQL 11 and restore it in your PostgreSQL 12. It the the time for everybody using PostgreSQL 9.6 to start planning an upgrade to the latest supported PostgreSQL version. With PostgreSQL, this used to be impossible in a native way. The function now allows reset of statistics for specific databases, users, and queries. kindly refer to the parameter reference as below: Here, In the same console, we add the upgrade log. At the end of the installation process, we can see the installation summary, which will showcase the user's user inputs during the installation process. There were a few Use pread() and pwrite() for random I/O (Oskari Saarenmaa, Thomas Munro).
