Обсуждение: vacuum schema

Is there a way to vacuum all tables in a schema? Or will I need to
write a script to do it?

-Josh

Are you looking for something different than vacuumdb?

I think so. As far as I can tell, you can either vacuum a whole db, or
individual tables. But not a whole schema.

Ah, yes. You're right.

Presumably you could use the hidden query from \dn in psql to get the
tables necessary for a script. That's the next best thing I can think
of.

I wrote a script to do the vacumming. I just have a config file where
you can list the tables you want vacuumed.

Can you use those tables via normal sql? It would be nice to do that via sql.

-Josh

Sure. The system tables can be accessed via SQL.

I frequently use the output of psql's hidden queries to glean more
information about postgres internals for needs like yours where
postgres has the information but not the interface to accomplish a
specific task.
