Hello,
we found a bug while testing the latest version of Hot Standby. Then
we could reproduce it on the unpatched HEAD, so we are going to ignore
it in the next few days.
During a Warm Standby session using current HEAD I obtained the
following error on the standby node:
---8<------8<------8<------8<------8<------8<------8<------8<------8<---

After setting up the session, I started an endless loop of "make
installcheck" on the primary node; the error happened after 40/50
minutes.
At the present I can't say exactly which test was responsible for
that, but this information should be obtainable by raising debug level
on the primary and comparing WAL segment numbers while looking at both
logfiles. Anyway, since the error was raised by bgwriter when running
with Hot Standby patch applied, is likely to be something to do with
the guts of checkpointing.
