Internal Server Error when loading Explorer tab (SDC #995) This is with reference to a weird scenarios where chunk table entry exist in timescaledb catalog but it does not exist in PG catalog. The stale entry blocks executing hypertable_size function on the hypertable. The changes in this patch are related to improvements suggested for hypertable_size function which involves: 1. Locking the hypertable in ACCESS SHARE mode in function hypertable_size to avoid risk of chunks being dropped by another concurrent process. 2. Joining the hypertable and inherited chunk tables with "pg_class" to make sure that a stale table without an entry is pg_catalog is not included as part of hypertable size calculation. 3. An additional filter (schema_name) is required on pg_class to avoid calculating size of multiple hypertables with same in different schema. NOTE: With this change calling hypertable_size function will require select privilege on the table. Disable-check: force-changelog-file
