Hi, everyone.
I saw some people talking about the reindex command and I read in the docs the one reason to use reindex is when a table is bloated.
But how do I know when a table is bloated?

You could use PGSTATTUPLE extension, which you could read about here:

--Does auto-vaccum do the reindex process for us?

No, autovacuum and reindexing are 2 completely different processes.
