http://bugzilla.opensuse.org/show_bug.cgi?id=1187392 http://bugzilla.opensuse.org/show_bug.cgi?id=1187392#c1 --- Comment #1 from Reinhard Max <max@suse.com> --- I need more details to narrow this down: - How was the database showing the crashes and duplicates created and populated (pg_upgrade, replication, restore of a dump, etc.)? - When was PostgreSQL being upgraded? - When was the OS upgraded from 15.2 to 15.3? - When did the first crash happen? I suppose the duplicate entries are due to the system upgrade that contains a glibc upgrade that comes with heavy changes to collations which in turn requires reindexing of all indexes on text columns in PostgreSQL that use one of the affected collations. This would be the case if the database was migrated using pg_upgrade along with the system upgrade, or if PostgreSQL was upgraded to 13 on 15.2 (regardless of the migration method) and the system upgrade happened afterwards.

They might be a consequence of the corrupted indexes, although I haven't yet heared of them causing crashes. I'd say let's address the corrupted indexes first and then see if the crashes still happen. -- You are receiving this mail because: You are on the CC list for the bug.
