Hi All;

I'm preparing to fire up WAL archiving on 8 production servers We will follow
up with implementing a warm standby scenariio.

Does anyone have any thoughts per how to maximize performance, yet minimize
the potential for data loss assuming we were not able to retrieve the final
un-archived WAL segment from the original pg_xlog dir in the case of a crash?

Specifically, I wonder if there are some general rules of thought per tuning
wal_buffers,  checkpoint_segments and friends...

Currently all servers have the following settings:
wal_buffers = 24
checkpoint_segments = 32


Thanks in advance

/Kevin
