Just to let you know that the patch itself doesn't affect the overall
design of PgPool. This was exactly what I want : not modify anything in
the way it actually works to not break anything and easy adoption of the
patch.

I don't see what's in Pg 9.1 can affect the patch unless there's a plan
for cascading replication but I don't think so.  Also we will not break
any PostgreSQL compatibility if this patch only affect streaming
replication, isn't it ?

Yes, no problem I've sent a lot of patches these last weeks and I know
that review can takes more time than coding.

Ok, I will do the work for this patch as well as the promote any node as
master patch.  Do you think this last one may be useful in other mode
than streaming replication ?

Whatever we can discuss all of that in Paris next week, I will be very
pleased to meet you.

Best regards,
