The capability to return composite types (multi-column rows) is limited in <=
PostgreSQL 7.2.x. What you are seeing are pointers to the rows, not the rows
themselves.
Version 7.3, in beta testing now, will do what you are looking for. If you
can, please give it a try. See:
http://developer.postgresql.org/docs/postgres/xfunc-tablefunctions.html
for more info and examples.
HTH,
Joe
