Hi all, When I try to analyze (or vacuum) the database with the owner of the database I receive the following warnings:
WARNING: skipping "pg_authid" --- only table or database owner can analyze

I checked at the documentation and found that those tables are shared across all of the databases of the cluster. So my question is, is it important to analyze/vacuum them? or maybe because they are scarcely used (I don't even know if this assumption is right) it's not important to analyze/vacuum them?
You'll need to vacuum often enough to prevent transaction wraparound. You might need to vacuum reasonably often if you create & drop a lot of system objects (databases/users etc) and end up with bloated tables.
I can always change their owner to the database owner but I guess that if the database owner didn't get ownership over those tables too then there is a reason for that...
Don't know if you could have a user other than postgres owning them. Not sure anyone's tried.
I think most people schedule their vacuum/autovacuum to run as "postgres" anyway - particularly if they have more than one database in an installation.
