-- If you migrated your PostgreSQL database from old to new schema using
-- previous ejabberd versions, your database may be missing the migration
-- steps for the push_session table. You can update it now with:

ALTER TABLE push_session ADD COLUMN server_host text NOT NULL DEFAULT '<HOST>';
DROP INDEX i_push_usn;
DROP INDEX i_push_ut;
ALTER TABLE push_session ADD PRIMARY KEY (server_host, username, timestamp);
CREATE UNIQUE INDEX i_push_session_susn ON push_session USING btree (server_host, username, service, node);

-- In the PostgreSQL new schema, the primary key for the vcard_search table
-- was wrong. How to update an existing database:

ALTER TABLE vcard_search DROP CONSTRAINT vcard_search_pkey;
ALTER TABLE vcard_search ADD PRIMARY KEY (server_host, lusername);
