If you use the 1.0CVS PostGIS, the jdbc2 JTS support should work for
basic operations (writing and reading data).

It still needs some polishing (proper use of GeometryFactories,
regression tests, updated SRID working etc.), but it should be quite
usable now (despite being still called experimental).

Any user feedback is appreciated.
