-- This script has to be used if you already

-- your database schema.
--
-- YOU DON'T NEED TO USE IT IF YOU'VE JUST INSTALLED PYKOTA
--

--
-- WARNING : YOU NEED A RECENT VERSION OF POSTGRESQL FOR THE ALTER COLUMN STATEMENT TO WORK !
--

--
-- Modify the old database schema
--
ALTER TABLE jobhistory ADD COLUMN jobprice FLOAT;
ALTER TABLE jobhistory ADD COLUMN filename TEXT;
ALTER TABLE jobhistory ADD COLUMN title TEXT;
ALTER TABLE jobhistory ADD COLUMN copies INT4;
ALTER TABLE jobhistory ADD COLUMN options TEXT;

--
-- Remove bad integrity rules
-- and replace them with a new one
--
ALTER TABLE jobhistory DROP CONSTRAINT "$1";
ALTER TABLE jobhistory DROP CONSTRAINT "$2";
ALTER TABLE jobhistory ADD CONSTRAINT checkUserPQuota FOREIGN KEY (userid, printerid) REFERENCES userpquota (userid, printerid);

--
-- Add new tables
--
--
-- Create the printer groups relationship
--
CREATE TABLE printergroupsmembers(groupid INT4 REFERENCES printers(id),
                           printerid INT4 REFERENCES printers(id),
                           PRIMARY KEY (groupid, printerid));

--
-- Now add some indexes
--
CREATE UNIQUE INDEX userpquota_up_id_ix ON userpquota (userid, printerid);
CREATE INDEX jobhistory_p_id_ix ON jobhistory (printerid);
CREATE INDEX jobhistory_pd_id_ix ON jobhistory (printerid, jobdate);
CREATE UNIQUE INDEX grouppquota_up_id_ix ON grouppquota (groupid, printerid);

--
-- And now sets some ACLs
--
REVOKE ALL ON printergroupsmembers FROM public;
GRANT SELECT, INSERT, UPDATE, DELETE, REFERENCES ON printergroupsmembers TO pykotaadmin;
GRANT SELECT ON printergroupsmembers TO pykotauser;
