Search the list archives (through groups.google.com - it's
comp.databases.postgresql) or see the developer docs for PL/pgSQL. You
can achive that effect by returning a cursor in PG 7.2 (the section on
returning cursors is ommitted from the current docs in
www.postgresql.org/idocs, so you need to look at the developer docs - see
www.us.postgresql.org).
