O.S.:
SuSE SLES-8 (i386)
VERSION = 8.1
After some test with the "syncbench" posted on performance mailing-list
(http://archives.postgresql.org/pgsql-performance/2004-09/msg00080.php)
i have obtained that open() with O_DSYNC was the fastest sync method.
I want to test this for parameter "wal_sync_method" on a test workload
directly on Postgres and i have configured that on postgresql.conf file:
wal_sync_method = open_datasync
But at the server start:
> pg_ctl -D /db10/postgres/data start
postmaster starting
> FATAL: invalid value for parameter "wal_sync_method": "open_datasync"
What's wrong?
Best regards.
