If you were just inserting directly into other child tables, a lock on either the parent or the target child table shouldn't affect them. I wonder if you are using conditional rules to redirect the inserts, and the rules include a reference to the target table? If that's the case, you really need to drop the relevant rule before you remove the child table, anyway. regards, tom lane
