[GENERAL] information_schema._pg_keypositions() in 8.1???
I cannot get automatic schema update to work in 8.1 with hibernate 3.0.5. I get the following error every time. java.sql.SQLException: ERROR: function information_schema._pg_keypositions() does not exist Is this something I should be looking to fix with Hibernate or PostgreSQL? Any assistance would be greatly appreciated. Thank you for your time, Jason Long CEO and Chief Software Engineer BS Physics, MS Chemical Engineering http://www.supernovasoftware.com

Executing the following from information_schema.sql from the 8.0 distribution against the restored database in 8.1 solved the problem. Is this a bug? * SET search_path TO information_schema, public; /* * A few supporting functions first ... */ /* This returns the integers from 1 to INDEX_MAX_KEYS/FUNC_MAX_ARGS */ CREATE FUNCTION _pg_keypositions() RETURNS SETOF integer LANGUAGE sql IMMUTABLE AS 'select g.s from generate_series(1,current_setting(''max_index_keys'')::int,1) as g(s)'; Thank you for your time, Jason Long CEO and Chief Software Engineer BS Physics, MS Chemical Engineering http://www.supernovasoftware.com From: [EMAIL PROTECTED] [mailto:[EMAIL PROTECTED] On Behalf Of Jason Long Sent: Thursday, December 01, 2005 11:43 AM To: pgsql-general@postgresql.org Subject: [GENERAL] information_schema._pg_keypositions() in 8.1???

Hibernate. As a short term workaround you could manually create the function using the 8.0 definition, which is /* This returns the integers from 1 to INDEX_MAX_KEYS/FUNC_MAX_ARGS */ CREATE FUNCTION information_schema._pg_keypositions() RETURNS SETOF integer LANGUAGE sql IMMUTABLE AS 'select g.s from generate_series(1,current_setting(''max_index_keys'')::int,1) as g(s)'; Note that one reason this went away in 8.1 is that there no longer is a hard upper limit to the number of function arguments, so depending on what Hibernate is expecting it to do, you might have some issues ... regards, tom lane ---(end of broadcast)--- TIP 3: Have you checked our extensive FAQ? http://www.postgresql.org/docs/faq

You need the 8.1 driver.
