Hi Tom, No row has granted='f'. The result shown in the original email is from: select c.relname, l.pid, l.mode, l.granted, current_query from pg_locks l, pg_class c, pg_stat_activity a where relation is not null AND l.relation = c.oid AND l.pid = a.procpid AND l.mode != 'AccessShareLock' order by l.pid;
After the above result, I went to OS to get ps status. Did I miss something? Since the lock was granted to pid (18951), that cause me confuse why OS ps shows it is waiting. Also, I ntoiced that insert will be finished almost immediately after delete is done.
