[postgis] idea for postgis application

[Paul Ramsey]

Any interactive viewer would be sweeeeet, although Mac-only might be a
bummer for linux'ers like myself. The main issue I forsee w/ interactive
viewers is avoiding the "crushing load" problem when people are looking
at large extents on large large tables. (All streams in British
Columbia, for example.)
