Hello,
When doing a pg_dump of one of our databases one of the tables primary keys doesn’t get exported. Pg_dump just skips this index, without any warning whatsoever (verbose mode was used to doublecheck).
When doing a REINDEX the issue is fixed.
As this seems to me to be some form of index corruption, I tried using amcheck (bt_index_check and bt_index_parent_check) to verify for corruption but both resulted with no issues (the index is a btree).
I would expect the corruption to show up when using amcheck, am I hitting some kind of bug here?
Does this problem keep happening, or has it only happened once?
Are there any other ways to doublecheck for corruption (without enabling checksum upfront)?
pg_checksums is available in PG 15.
This concerns a PostgreSQL version 15 btw.
Are you at the current patch level?
