Hello, Lonni
I use rsync to transfer the files (pg_xlog) from master to slave.rsync -Crap %p postgres@slaveaddress:/slavetransactionlogs/%f
In my recovery.conf (slave) I have the following statement:
restore_command = 'test -f $slavetransactionlogs/%f && cp $slavetransactionlogs/%f %p'
Best Regards

If you're not running pg_basebackup with the -x option, how are you
getting the WAL files onto the slave?
