New Revision: 13926

Modified:
   trunk/Open-ILS/src/sql/Pg/200.schema.acq.sql
Log:
Change constraint on acq.provider.  Instead of making code unique
by itself, make code + owner unique.

To change an existing table:

ALTER TABLE acq.provider
DROP CONSTRAINT provider_code_key;

ALTER TABLE acq.provider
ALTER COLUMN code SET NOT NULL;

ALTER TABLE acq.provider
ADD CONSTRAINT code_once_per_owner
	UNIQUE (code, owner);
