Hi All, We are having a partition table and we are querying some rows in the partition. select * from events where events.evt_time >= '2010-11-29 00:00:00' AND events.evt_time <= '2010-11-30 23:59:59' While this query is in running state, I am issuing a drop statement on a partition of this table. drop table events_p_20101207130000 Please note that the query is running on a different partition and drop is happening on a different partition. Now, in a different session, I am running a different query, select * from events where events.evt_time >= '2010-11-28 00:00:00' AND events.evt_time <= '2010-11-29 23:59:59' Now the issue is both the drop and my 2nd query is in waiting state and both these queries started running after my first queries completion. We have set constraint_exclusion to on and we used, select * from pg_stat_activity where waiting = 'true' query to check the status of the waiting queries. Now, can you please explain me on why it is behaving like this. Is this a postgres bug or any configuration needs to be done to avoid this waiting. Any help is really appreciated.
