Status Report: I will finish documentation and review tomorrow and will mark this patch for committer review.
Here's my latest reviewed version of Pavel's patch with adjusted documentation per latest discussion.
While poking a little bit with simplify_function() I realized that this patch changes the behavior of VARIADIC functions a little bit. For example:
CREATE OR REPLACE FUNCTION my_test(a IN text, txt VARIADIC text[])
RETURNS text
AS
$$
SELECT $2[1];
$$ LANGUAGE SQL;
The following doesn't work in current 8.4:
SELECT my_test('abcd', ARRAY['test', 'foo']);
You need to use the VARIADIC keyword to match the second argument to
text[]. However, if you are going to use named notation with the patch
applied, the picture changes in HEAD:
SELECT my_test('abcd' AS a, ARRAY['test', 'foo'] AS txt);
my_test
---------
test
(1 row)
This applies also when you reverse the argument order. I don't know wether
this is intended, but its conflicting with what we have currently in the
docs. It's also not clear to me wether we want this at all.
