Change initdb default to enable data checksums (Greg Sabino Mullane) \u00a7
\nChecksums can be disabled with the new initdb option --no-data-checksums. pg_upgrade requires matching cluster checksum settings, so this new option can be useful to upgrade non-checksum old clusters.
Change time zone abbreviation handling (Tom Lane) \u00a7
\nThe system will now favor the current session's time zone abbreviations before checking the server variable timezone_abbreviations. Previously timezone_abbreviations was checked first.
Deprecate MD5 password authentication (Nathan Bossart) \u00a7
\nSupport for MD5 passwords will be removed in a future major version release. CREATE ROLE and ALTER ROLE now emit deprecation warnings when setting MD5 passwords. These warnings can be disabled by setting the md5_password_warnings parameter to off.
Change VACUUM and ANALYZE to process the inheritance children of a parent (Michael Harris) \u00a7
\nThe previous behavior can be performed by using the new ONLY option.
Prevent COPY FROM from treating \\. as an end-of-file marker when reading CSV files (Daniel V\u00e9rit\u00e9, Tom Lane) \u00a7 \u00a7
psql will still treat \\. as an end-of-file marker when reading CSV files from STDIN. Older psql clients connecting to PostgreSQL 18 servers might experience \\copy problems. This release also enforces that \\. must appear alone on a line.
Disallow unlogged partitioned tables (Michael Paquier) \u00a7
\nPreviously ALTER TABLE SET [UN]LOGGED did nothing, and the creation of an unlogged partitioned table did not cause its children to be unlogged.
Execute AFTER triggers as the role that was active when trigger events were queued (Laurenz Albe) \u00a7
Previously such triggers were run as the role that was active at trigger execution time (e.g., at COMMIT). This is significant for cases where the role is changed between queue time and transaction commit.
