-- Citus upgrades are finished by calling a procedure

-- Note that pg_catalog.citus_finish_citus_upgrade() behaves differently
-- when last upgrade citus version is less than 11
-- so we have two alternative outputs for this test
\set upgrade_test_old_citus_version `echo "$CITUS_OLD_VERSION"`
SELECT substring(:'upgrade_test_old_citus_version', 'v(\d+)\.\d+\.\d+')::int < 11
AS upgrade_test_old_citus_version_lt_11_0;

-- this is a transactional procedure, so rollback should be fine
BEGIN;
	CALL citus_finish_citus_upgrade();
ROLLBACK;

-- do the actual job
CALL citus_finish_citus_upgrade();

-- show that the upgrade is successfull

SELECT metadata->>'last_upgrade_version' = extversion
FROM pg_dist_node_metadata, pg_extension WHERE extname = 'citus';

-- idempotent, should be called multiple times
-- still, do not NOTICE the version as it changes per release
SET client_min_messages TO WARNING;
CALL citus_finish_citus_upgrade();

-- we should be able to sync metadata in nontransactional way as well
