[GENERAL] user privilages for executing pg_autovacuum?

[Zlatko Matić]

For pg_dump minimum privilages is to have select right on tables. For vacuumdb, one must be owner of tables or a superuser.   What are minimum rights for user that is trying to execute pg_autovacuum ?   How can I monitor vacuuming by pg_autovacuum ?   Thanks,   Zlatko
