blocking_activity.query AS current_statement_in_blocking_process
FROM pg_catalog.pg_locks blocked_locks 
JOIN pg_catalog.pg_stat_activity blocked_activity ON blocked_activity.pid = blocked_locks.pid
JOIN pg_catalog.pg_locks blocking_locks 
ON blocking_locks.locktype = blocked_locks.locktype 
AND blocking_locks.DATABASE IS NOT DISTINCT FROM blocked_locks.DATABASE

AND blocking_locks.objid IS NOT DISTINCT FROM blocked_locks.objid
AND blocking_locks.objsubid IS NOT DISTINCT FROM blocked_locks.objsubid
