Hi.  Replication lags over 5 minutes behind (sometimes over 10 minutes
behind) while pg_dump is running on the slave.

We monitor our replication lag using Bucardo's check_postgres.pl and
it keeps showing up on the monitoring/alerting radar 4 times a day,
when we do the pg_dump.

I've increased the alert threshold to 30 minutes as an immediate
measure, but is there any way to reduce pg_dump's impact on
replication?  or will we pretty much have to live with it?

Best,
