Hackers,
Given this script on 9.1beta3:
BEGIN;
CREATE EXTENSION plperl;
CREATE OR REPLACE FUNCTION wtf(
) RETURNS TEXT[] LANGUAGE plperl AS $$ return []; $$;
SELECT wtf() = '{}'::TEXT[];
ROLLBACK;
The output is:
BEGIN
CREATE EXTENSION
CREATE FUNCTION
?column?
----------
f
(1 row)
ROLLBACK
Why is that? If I save the values to TEXT[] columns, they are still not the
same. But if I pg_dump them and then load them up again, they *are* the same.
The dump looks like this:
CREATE TABLE gtf (
have text[],
want text[]
);
COPY gtf (have, want) FROM stdin;
{} {}
\.
Is PL/Perl doing something funky under the hood to array values it returns on
9.1?
Thanks,
David
