pg_dump and truncate

From

Hi:

   While pg_dump is dumping my database, I find that when I try to truncate
a table the query hangs.  Is that the expected behavior?  What if I try
to drop a table? Will that hang as well?

Thanks as always!

Yes. dump grabs an AccessSharedLock on everything it's going to dump.
