Those tables belong to a *different* module, though. I'm picturing
three modules here: pljava, postgis, and a postgis-pljava support
module that requires the first two, since it should be possible to
install postgis without requiring pljava. The above stuff was from the
install script of the postgis-pljava code, but inserted data into
tables owned by pljava.
