Long running queries on the standby are a bit tricky, because they
might need to see row versions that are already removed on the
master.
It's well documented:
http://www.postgresql.org/docs/9.0/static/hot-standby.html
Right. I read all of that. I guess I just assumed it was possible to create a snapshot on the standby so that a longer running on the standby could complete. In particular, I was really hoping to run database dumps against the standby, not the master.
Thanks.
