Try "SQL Functions Returning Sets" here:
http://www.postgresql.org/docs/8.1/static/xfunc-sql.html
In plpgsql you just "RETURN NEXT" each value (typically this would
be inside a loop, though it doesn't have to be) and then either
RETURN with no argument or fall off the end of the function (I think
the latter is only allowed as of PG 8.1). There don't seem to be
any very compelling examples in the manual, but I bet you can find
some at techdocs.postgresql.org.
