I'm not sure I exactly understand, but you can probably find
something on this page that will help:
 
http://www.postgresql.org/docs/8.4/interactive/sql-revoke.html
 
Perhaps this?:
 
REVOKE ALL ON SCHEMA x FROM y;
 
> I also need to disconnect users who are accessing the system.
 
http://www.postgresql.org/docs/8.4/interactive/functions-admin.html#FUNCTIONS-ADMIN-SIGNAL-TABLE
 
Before using these functions, you probably want to modify the
pg_hba.conf file and signal a reload, to block new logins.
