Обсуждение: review: table function support

Generally, the patch looks fine.  There are few issues still:

- plpgsql: the result columns _do_ create local variables. AIUI, they should not?

- pg_dump: is the psql_assert() introduction necessary, considering it is used only in one place?

- There should be regression test for plpgsql too, that test if the behaviour is correct.

- The documentation should mention behaviour difference from OUT parameters.

Wishlist (probably out of scope for this patch):

- plpgsql: a way to create record variable for result row.  Something like:
   CREATE FUNCTION foo(..) RETURNS TABLE (..) AS $$   DECLARE      retval   foo%ROWTYPE;

 Currently the OUT parameters are quite painful to use due to bad name resolving logic.  Such feature would be perfect
replacement.
