data from system tables.

[Carol Walter <walterc(at)indiana(dot)edu>]

Hello,

We recently began giving our users a ten connection limit.  The are  
some accounts that have no limit.  Some of these should have no limit  
because they're system accounts, but others are just users that were  
created before we started the limit.  Is there a psql command that I  
can run with a "where" clause that will let me get a list of everyone  
who has no connection limit?
