There is an awkward way of doing this in Postgres 7.2.1, involving CURSORS.
In 7.3, which will be out in beta sometime soon, it will be possible to have
T-SQL-like row-returning Functions.

There is one other difference btw. Postgres Functions and MSSQL Procedures;
Postgres functions may be called within a query, and MSSQL procdedures may
not.  On the other hand, MSSQL procedures may return multiple result sets,
and I don't think anyone is proposing this for Postgres.
