In current releases, you'll have to create a named composite type that
matches what you want to return, and declare the function as returning
that type.
(PG 8.1 will have a facility for named OUT parameters that lets you
avoid the notational overhead of inventing a composite type, although
what happens under-the-hood is not really very different.)
