recovery.signal and standby.signal files are now used to switch into non-primary mode. It is based on a publish and subscribe mode, where one or more subscribers subscribe to one or more publications on a publisher node. This is undesirable since depending on usage, the whitespace might be considered semantically significant. Use of these options reduces VACUUM's locking requirements, but prevents returning disk space to the operating system. Domains that are being used purely as type aliases no longer cause optimization difficulties. The walsender process starts logical decoding of the WAL and loads the standard logical decoding plugin. optimization for VACUUM when CREATE INDEX CONCURRENTLY and REINDEX CONCURRENTLY were By submitting my information I agree that Percona may use my personal data in sending communication to me about Percona services. and one issue is specific to the May 12, 2022 release You do need to weigh the Sign up for a free GitHub account to open an issue and contact its maintainers and the community. Support use of images in the PostgreSQL documentation (Jrgen Purtz), Allow ORDER BY sorts and LIMIT clauses to be pushed to postgres_fdw foreign servers in more cases (Etsuro Fujita), Improve optimizer cost accounting for postgres_fdw queries (Etsuro Fujita), Properly honor WITH CHECK OPTION on views that reference postgres_fdw tables (Etsuro Fujita). This is useful for routines that only need to examine the initial portion of a toasted field. This can be optimized when the table's column constraints can be recognized as disallowing nulls. Version 12 contains a number of changes that may affect compatibility with previous releases. The pg_hba.conf file also needs to be adjusted to allow replication. Such expressions are evaluated at partitioned-table creation time. Specifically, recovery_target_timeline now defaults to latest. This column has been deprecated for a long time, because it did not update in response to other catalog changes (such as column renamings). These parameters are archive_cleanup_command, promote_trigger_file, recovery_end_command, and recovery_min_apply_delay. On the subscriber side, it also requires the max_replication_slots to be set. By clicking Sign up for GitHub, you agree to our terms of service and This is a major release, so it requires some effort to upgrade. Once you have your schema in PostgreSQL 12, you need to create the subscription, replacing the values of host, dbname, user, and password with those that correspond to your environment. to understand what fixes are available, and test your applications against the As described, Percona is an open source database software, support, and services company that helps make databases and applications run better. In some cases, these functions would insert extra whitespace (newlines and/or spaces) in nodeset values. Upgrade PostgreSQL 9.4 to 11 or 12 #2801 - Github We can clearly see that there are 22 tables and view types of objects that are residing in the dvdrental database. See Section18.6 for general information on migrating to new major releases. So based on this, lets configure the publisher (in this case the PostgreSQL 11 server) as follows: You must change the user (in this example rep1), which will be used for replication, and the IP address 10.10.10.131/32 for the IP that corresponds to your PostgreSQL 12 node. Allow the extra_float_digits setting to be specified for pg_dump and pg_dumpall (Andrew Dunstan). Mark table columns of type name as having C collation by default (Tom Lane, Daniel Vrit), The comparison operators for data type name can now use any collation, rather than always using C collation.
