This patch brings the JDBC driver up to the current protocol spec.
Basically, the backend now tells the driver what authentication scheme to
use.
The patch also fixes a performance problem with large objects. In the
buffer manager, each fastpath call was sending multiple Notifications to
the backend (sometimes more data in the form of notifications were being
sent than blob data!).
I've found a problem in the Postgresql jdbc driver.
"ReceiveInteger" shifts a received byte right instead of left.
This means that only the least significant byte is read into the int.
