Where can we find bug information? Huh? PostgreSQL is open source. I told you it is commit fa675af59f, so you can look at https://git.postgresql.org/gitweb/?p=postgresql.git;a=commitdiff;h=fa675af59f It is also listed in the release notes of 13.4: https://www.postgresql.org/docs/13/release-13-4.html - Harden B-tree posting list split code against corrupt data (Peter Geoghegan) Throw an error, rather than crashing, for an attempt to insert an item with a TID identical to an existing entry. While that shouldn't ever happen, it has been reported to happen when the index is inconsistent with its table. Yours, Laurenz Albe
