This is from Slony? You know that that's a built-in limitation, and
that the preferred method is switchover, right? Failover should be
the last result. (Also, you'll get better results if you discuss
this on the slony list.)

Slony knows nothing about the WAL-archiving backup method. When you
subscribe a datbaase, it automatically drops and recreates the target
from scratch. There has been some discussion of how to improve that,
but AFAIK nobody has written the support for it yet.
