The issues listed below affect PostgreSQL 17. Some of these issues may
also affect other supported versions of PostgreSQL.
- Restore functionality of ALTER ROLE .. SET ROLE and ALTER DATABASE ..
SET ROLE. The fix for CVE-2024-10978 accidentally caused settings for
role to not be applied if they came from non-interactive sources,
including previous ALTER {ROLE|DATABASE} commands and the PGOPTIONS
environment variable.
- Restore compatibility for the timescaledb and other PostgreSQL
extensions built using PostgreSQL prior to the 2024-11-14 release
(17.0, 16.4, 15.8, 14.13, 13.16, 12.20, and earlier). This fix restores
struct ResultRelInfo to its previous size, so that affected extensions
don't need to be rebuilt.
- Fix cases where a logical replication slot's restart_lsn could go backwards.
- Avoid deleting still-needed WAL files during pg_rewind.
- Fix race conditions associated with dropping shared statistics
entries, which could lead to loss of statistics data.
- Fix crash with ALTER TABLE when checking to see if an index's opclass
options have changed if the table has an index with a non-default
operator class.
