This symptom matches an old bug that was fixed in PG 9.6.9. So

(1) Are you quite sure your server is running 9.6.12, and not some
older minor release? Check "SELECT version()" to be certain.

(2) According to the release note about it, any pre-existing
corruption of this sort could be repaired by vacuuming affected
tables. So maybe you just need to do that.
