I want to disable Write Ahead Log (WAL) completely because of following reasons,
I am running Linux on the Compact Flash, which has limited memory; I can’t afford disk space of 32MB for pg_xlog folder. ( checkpoints_segments = 1)
CF has own limitation with respect to number of writes (I/O operation).
And, Our Database is Small and embedded as part of system (along with web-server, drivers). We may not require data recovery from the pg_xlog folder. It is not an enterprise application.
