It sounds to me like Oliver's original patch would solve most all
'normal' cases reasonably well, including the case when people would
want all PreparedStatements to be server-side prepared via setting the
threshold to 1. It would not solve the 'fight-the-middleware
cross-PreparedStatement pooling' scenario I face, but it sounds like a
little-to-loose patch -- backwards compatibility is maintained, and you
can get server-preparation without downcasting if so desired, either
always or past a static barrier.

Is it a candidate for commitment?
