I've been looking at this, and my feeling is that we should drop the
PROARGMODE_TABLE business and just define RETURNS TABLE(x int, y int)
as exactly equivalent to RETURNS SETOF RECORD with x and y treated as
OUT parameters.  There isn't any advantage to distinguishing the cases
that outweighs breaking client code that looks at pg_proc.proargmodes.
I don't believe that the SQL spec prevents us from exposing those
parameter names to PL functions, especially since none of our PLs are
in the standard at all.
