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
themup 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
