I tried this from pg_admin, but I get a syntax error (unexpected character)
IF EXISTS (SELECT 0 FROM pg_class
WHERE relkind = 'S'
AND oid::regclass::text = 'public.' || quote_ident('hibernate_sequence'))
THEN
RAISE EXCEPTION 'sequence public.% already exists!', 'hibernate_sequence
ENF IF;
Thanks.

Subject: Re: [ADMIN] checking if sequence exists
How can we find out if a particular sequence exists ? The idea is to check if sequence first and if it does not exist then create it...the goal is to do this when we deploy the application war...
thanks
