I would just like to get some clarification from the list on how to do a pg_dump on the slave in the face of "canceling statement due to conflict with recovery".
The following links seem to indicate that If I start an idle transaction on the master I should be able to do the pg_dump, but I tried this in psql on the master "start transaction", and was still unable to do a pg_dump on the slave at the same time.
Is there something special about using dblink that would make this all work?

http://postgresql.1045698.n5.nabble.com/Hot-Standby-ERROR-canceling-statement-due-to-conflict-with-recovery-td3402417.htmlOne solution is to begin idle transactions on the master by using e.g. dblink from the standby to the master before you start pg_dump on the standby and end them after pg_dump (or whatever) is finished.
