Hey Rob, this worked great! Thanks for the quick response. One other thing I'm noticing is that the generalizing that there seems to be a default, non-zero value for "simplify"... I removed that parameter because simplifying adjacent polygons created gaps at some zoom levels. However, it wasn't until I explicitly set "simplify":0 that it actually rendered without any simplification. Ultimately, it would probably be best to make a separate postgis that has the outlines as lines, not polygons, and add that into the mix.
