You can limit access to individual databases in a cluster by ip address
or username (both postgres username and host username). This is done in
pg_hba.conf.

You can also limit access to objects by postgres username and group.
This includes databases, schemas, tables, views, functions, sequences and
probably a few other things. You can't directly restrict access to rows or
columns of a table. You can create views that can only be used by some
users or groups that restrict access to rows and or columns of a table.
