The bottleneck in my application now looks to be
ST_SimplifyPreserveTopology(). I'm finding that it's often best to do
computation outside the database. However, one thing that Java2D is
missing is a polygon simplification function. I might look to see if
Geotools has one.
The original code for ST_SimplifyPreserveTopology comes from JTS. You
can either use the library directly, or try JEQL for a command-line
interface to it. You can find both at http://tsusiatsoftware.net/
