Well, so I need to do reindex frequentely in database? Is that right?
Or should I use cluster, as David said?
How frequently should I do this operation?

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:

No, autovacuum and reindexing are 2 completely different processes.
