I think what Tom is saying is that you'll be able to set
prepareThreshold to 1 in the driver (always use named server-side
prepared statements) and the server will automagically do the right
thing. Right now, the big problem is that only unnamed prepared
statements include the "feature" of being able to consider parameters
in the query plan (since unnamed statements are not reused, there's no
sense in planning them before you have parameters). Other aspects of
using prepared statements through the jdbc driver wouldn't change, but
we should be able to forget about prepareThreshold (if I understand
this correctly), which would be very nice.
