Folks,

I'd like to take a whack at making set-returning functions returning
SETOF RECORD a little more fun to use.  Let's imagine that we have a
table foo and a function returning SETOF RECORD that can return foos.
The call might look something like:

SELECT a, b, c
FROM f(ROW OF foo)
WHERE ...;

This would make it much easier and less error-prone to use SETOF
RECORD.

Would others like to see such a feature?

If so, what pieces of the code would I be touching for the first
patch?

Cheers,
David.
