Thanks for your detailed answer. I don't want to do anything wrong. To be
sure, i have some more questions:
- There is no entry in pg_depend. Should i just drop the entry from pg_type or
should i REINDEX anyway?
- Can i REINDEX pg_depend in normal operation mode or do i have to take
precautions mentioned in the docs? [1]
- How can things like this happen? Hardware failure? If yes, should i change
my harddisk?
kind regards,
Janning
[1] It's not clear to me if pg_depend is a "shared system catalog" because the
docs say
"any of the shared system catalogs (pg_database,
pg_group, pg_shadow, or pg_tablespace)"
Maybe the iteration is final, maybe it shows only examples)
