Commit cd7b204 by Álvaro Herrera blocks direct use of the pg repack logical decoding plugin outside of proper repack operations, after reports showed it caused assertion failures in debug builds and crashes in production due to memory…
Buffer management also saw important safety improvements. Fujii Masao's commit b70d567 restored row type verification in the pg buffer cache pages function, fixing a regression where incompatible caller-supplied record descriptors could crash the system instead of returning clean errors. Separately, Michael…
Finally, psql's describe functionality received missing schema qualifications to ensure proper namespace handling, addressing oversights from both recent and older commits dating back to version 15.
These fixes collectively strengthen PostgreSQL's defensive programming, turning potential crashes into proper error messages and…
