Yep, it certainly does. There's a command line tool that renders an XML map
declaration to a map (nik2img), and there's the main mapnik APIs
(C++/Python)

There's also some projects that start with OSM data and produce printed
maps. eg. with street-name indexes, mostly using mapnik for the
map-rendering part.

http://wiki.openstreetmap.org/wiki/OSM_on_Paper
specifically walkingpapers, maposmatic, and townguide.

It probably wouldn't be too hard to hack on them to use your postgis data
instead of OSM data.

The mapnik mailing lists are pretty friendly & helpful too.

HTH,

Rob :)
