Hi,
I was reading trough the ToDo list in the Postgres Wiki and noticed that one item for Fsync[1] seems to be obsolete:
Determine optimal fdatasync/fsync, O_SYNC/O_DSYNC options and whether fsync does anything
Ideally this requires a separate test program like /contrib/pg_test_fsync that can be run at initdb time or
optionallylater.
This was added with 9.1[2] , so I guess that item can be removed from the Wiki page?
Regards
Thomas
