Since it's an identifier and not really a numeric per se, I'd store it as text. I mean it could as easily be a 5 character alpha code as 5 character number code. With tet you can create indexes on substring(idfield,1,1), substring(idfield,1,2), substring(idfield,1,3), substring(idfield,1,4), and substring(idfield,1,5) for fast lookups and matching. -- Sent via pgsql-sql mailing list (pgsql-sql@postgresql.org) To make changes to your subscription: http://www.postgresql.org/mailpref/pgsql-sql
