I revised the idea with MINIMAL XLOG (instead of WITHOUT XLOG) like the
below. I think in this way, we can always gaurantee its correctness and
can always improve it.

To Use It
----------
A "BEGIN TRANSACTION MINIMAL XLOG/END" block is a speicial "BEGIN/END"
transaction block. It tries to avoid unnessary xlogs but still perserves
transaction semantics. It is good for the situation that the user wants to
do a big data load. It is issued like this:

	1. BEGIN TRANSACTION MINIMAL XLOG
	2.	...	/* statements */
	3. END;
