This isn't the same thing as allowing RETURNING inside subqueries,
right?

Allow SQL-language functions to return the output of an INSERT/
UPDATE/DELETE
RETURNING clause, not just a SELECT as formerly.

A side effect of this patch is that when a set-returning SQL
function is used
in a FROM clause, performance is improved because the output is
collected into
a tuplestore within the function, rather than using the less efficient
value-per-call mechanism.
