Your getting me excited about 6.5.  Is there a projected release date for
6.5?  Is there any information on transaction logging?  Is there anything I
can do to help?  I am curious about these items because they will make my
life much easier in the upcoming months as I migrate my application to
Postgres.  Working around these could be very difficulty or near impossible.

	MVCC locking in 6.5.  Will do what you need.

	Hard to explain.  Will wait or update a copy while read's use an
	copy fo the row.
