recordset?

If you have a table foo you can define your function with "returns foo" but
you cannot use this like:

select foo_function('x');

At present it is only useful for use by other functions (I believe). I think
Tom said this is on the developer todo list though, so sometime after 7.1 it
should be possible.

It would be nice to have this feature in next release. I cannot port my
applications to PostgreSQL without it. All my data objects depend on
recordset returned from stored procedures. Could someone consider it for
7.1? Thanks.
