Yes, fsync_method shouldn't be uncommented unless you're prepared to put
in the same default value presently computed in xlog.c. (Now that
initdb is in C, it might not be unreasonable to move the #ifdef hacking
that's in xlog.c over to initdb...)

Also you'd need to make some other adjustments in initdb; IIRC it does
sed-like substitutions that will break if the input is not just so.
I don't recall at the moment but there may be some things of the same
ilk done during "make install". And check the documentation to see if
any discussion needs updated.

No reason Greg can't do it if he wants to ... but the .sample file
itself is certainly not all that needs changing.
