Newb question.
I'm running 9.1 with a slave using streaming replication. A coworker wants
to turn off fsync on the master and insists that the slave will still be in
a usable state if there is a failure on the master. We all know that
turning off fsync is a bad idea, but I was under the impression that the
fsync setting would be replicated to the slave, making it useless as a
backup in this scenario. Am I wrong? If I'm wrong, is there still danger to
the slave in this kind of setup? Can I count on it remaining unharmed if
the master suffers unrecoverable corruption?
