[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
Re: [GENERAL] information_schema._pg_keypositions() in 8.1???
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)';

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.

Hm, it looks like some bright soul at Hibernate decided to depend on an
undocumented internal function :-(

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 ...

You need the 8.1 driver.
