Right.  Without the xlog directory you'll have very little chance of
ever doing any kind of clean stop/start of your database.  If you
don't need the reliability offered by Postgres's use of transaction
logs you'll probably be much better served with a different database
or even a completely different storage scheme than trying to make
Postgres fit that bill.
