This are some known issues using the new type-checking with the
server-side prepared statements for pgjdbc8.0. As far as I remember from
the pgjdbc mailing list, those should be fixed using the new build 310
of pgjdbc (postgresql-8.0-310.jdbc3.jar).

Note that this does not only affect PostGIS, but all the other
setObject() users, too. I still do not fully know all the details and
implications of this changes.

If build 310 does not work for you, you could temporarily use the latest
pgjdbc-7.4 jar, which should work fine against an 8.0 server. This
should you allow you to continue your work, while we in parallel try to
resolve your issues here and on pgsql-jdbc at postgresql.org.

Maybe I should add some regression tests for this cases?

Thanks. :-)
