OK, here's a pull request with a unit test to cover expected behaviour with
different combinations of setObject and setString, for inserts and queries.

https://github.com/pgjdbc/pgjdbc/pull/68

Interestingly, when I first tried this I tried using point as the type to
test rather than an enum (so that I didn't have to create the enum type in
the test), but it would fail when trying to select a row out in a query
like "select * from thetable where p = ?" saying "operator does not exist:
point = unknown". I presume that this due to multiple = operators for the
point type at the db level, so the backend can't decide which type to
create. I guess there's not much that we can do about that - if things are
ambiguous then you need to be more specific, and of course we have a
PGpoint java object anyway.
