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);
