Yes, but as I noted, I don't use temp tables at all.  If this is the
primary justification, then its not doing me any good, and causing
unnecessary negative performance impact.

I understand if this isn't something you can fix right now, but I'm
not even getting the impression that you consider this to be a design
flaw.  A high write volume on the master should never impact the
response time of any standby/slave with a read query.  This literally
means that pgpool doesn't scale well in write heavy environments.
