I realized after i sent this message that i might get this responese.
I should have mentioned this was from within a stored pl/pgsql
function, and the date wasn't a constant, but a variable. I was just
trying to simplify the example.

it's more like:

declare
foo_date date;
begin
select some_date into foo_date from some_table where something =
something_else;

select blah from redir_log where redir_timestamp >=
foo_date::timestamp without time zone at time zone 'GMT';
etc / etc / etc
end;
