One way to limit which users can access specific database is with the pg_hba.conf file.
You really should spend some time to read it.
http://www.postgresql.org/docs/8.1/interactive/client-authentication.html#AUTH-PG-HBA-CONF

In PostgreSQL 8.1 the concept of "Roles" were added.  A "Role" can be given specific privileges to
the database.  Once this step is complete, database uses can be assigned to this role.  This will
essentially inherit all role privileges to these users.  There is also an important document that
should be read in order to understand it.
http://www.postgresql.org/docs/8.1/interactive/user-manag.html

The SQL syntax for assigning privileges is found here:
http://www.postgresql.org/docs/8.1/interactive/ddl-priv.html

Also finding these topic is very easy also. Simple scan over the table of contents of the manual:
http://www.postgresql.org/docs/8.1/interactive/index.html

And of-course depending on what version of PostgreSQL you have:
http://www.postgresql.org/docs/manuals/
