I thought it got fixed here:
2008-05-14 10:02 mha
* src/backend/access/transam/xlog.c: Remove the special variable
for open_sync_bit used in O_SYNC and O_DSYNC modes, replacing it
with a call to a function that derives it from the sync_method
variable, now that it has distinct values for these two cases.
This means that assign_xlog_sync_method() no longer changes any
settings, thus fixing the bug introduced in the change to use a guc
enum for wal_sync_method.
Hmm ... or at least more or less fixed. Seems like there's no provision
to close and reopen the file if enableFsync changes. Not sure if that's
worth worrying about.
