Sorry. To me "latest" always defaults to HEAD and by "greatest" I mean
the coming 8.1.

Ok. Thanks. I'll redirect this to hackers and see if I have any luck
there. My original question was:

I do the following:

CREATE FUNCTION xyz(int, int) RETURNS RECORD AS '...'
CREATE TABLE abc(a int, b int);

Now I want to call my xyz function once for each row in abc and I want
my RECORD to be (x int, y int, z timestamptz). How do I write that
query? I.e. where do specify my RECORD definition? Is it possible at
all? Ideally I'd like to write something like this:

SELECT xyz(a, b) AS (x int, y int, z timestamptz) FROM abc;

but that yields a syntax error.
