Обсуждение: vacuum of pg_attribute and other infrastructure tables
Good morning,
I would like to vacuum full pg_attribute and some other postgres infrastructure tables to eliminate bloat. Could you please confirm that the recommended method to do this is to
stop postgres, restart in single user mode, and issue the vacuum command?
Thank you,
Mark

That is not necessary. Just run the VACUUM (FULL) as superuser. Concurrent access to pg_attribute will be blocked, which means that the database is pretty much unusable, but you don't need single user mode.
