Hi. When pg_dump runs, our application becomes inoperative (too slow). I was going to ask if nice'ing the postgres backend process that handles the COPY would help but I just realized probably the pg_dump takes out locks when it runs and nice'ing it would just make it run longer... However the man page says "pg_dump does not block other users accessing the database (readers or writers)." But if we run a pg_dump, the phone starts ringing, users are complaining that the web app is not working. Would appreciate some pointer to help me reconcile these two apparently contradictory facts.
