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).
What is the complete table definition?
What is the complete pg_dump command being given?
Is the PK definition in the pg_dump file?
For plain text format can you grep/find it?
For custom format does:
pg_restore -s -t <the_table> <dump_file>
show it?
How is the dump file being restored?
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?
Are there any other ways to doublecheck for corruption (without enabling
checksum upfront)?
This concerns a PostgreSQL version 15 btw.
Thanks!
