The other big useful feature we're missing from Functions is multisets.
Not only would they be generally useful for SP programming, but multisets
would eliminate one of the big hurdles in re-writing T-SQL stored
procedures in PG, and thus make it easier to port from SQL Server. You
don't hear a lot of demand for multisets on the mailing lists because
we're not getting those SQL Server / Sybase crossovers now.
Of course, Pavel can implement one of these features at a time ...
