Hi,
I want to disable Write Ahead Log (WAL) completely because
of following reasons,
1. 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)
2. CF has own limitation with respect to number of writes (I/O
operation).
3. 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.
Please give your inputs, to resolve this issue..
Thanks,
Jeeva...
