Re: Hot standby, overflowed snapshots, testing

Hi Simon and Heikki,

I can help set up automated basic tests for hot standby using 1+1 setups on
Amazon. I¹m already working on tests for warm standby for our commercial
Tungsten implementation and need to solve the problem of creating tests that
adapt flexibly across different replication mechanisms.

It would be nice to add a list of test cases to the write-up on the Hot
Standby wiki (http://wiki.postgresql.org/wiki/Hot_Standby) I would be
happy to help with that effort.

Cheers, Robert
