My current approach is what Fernando suggested -- use setArray() and look
for a preceeding IN. This can work without needing any postgres specific
classes -- I'll add a simple implementation of java.sql.Array that wraps a
Java array to the driver source, but if you don't want to be dependent on
the driver you can provide your own implementation.
The interface-abstraction argument only really works up to the point where
you want to do something not defined in the interface. Usually when I'm
doing DB-specific extension stuff I have a per-DB subclass that does the
special bits; if you don't have the driver available, you don't compile that
subclass. So I don't really buy the "can't build" argument. The same
thing applies to extensions like setUseServerPrepare(), BTW.
