ISTM xlog.c is clearly the *wrong* place; if this behavior has anything
to do with WAL logging as such, it's not apparent to me.  fd.c is not
a great place perhaps, but in view of the fact that we have things like
RemovePgTempFiles() in there, it's not unreasonable to see fsync_pgdata
as something to put there as well (perhaps with a name more chosen to
match fd.c names...)

Since Robert appears to be busy worrying about the multixact issue
reported by Steve Kehlet, I suggest he focus on that and I'll take
care of getting this thing committed.  AFAICT we have consensus on
what it should do and we're down to arguing about code style.
