gpsdrive has two ways to use the postgis database:
the one is for map rendering, which is done entirely by mapnik; gpsdrive 
requests the map data from mapnik, and has no direct database connection.

the other one is a direct connection with gda.
it is currently used to get the poi data and (experimental) street name 
display. a future use will be place/streetname/address search, which is 
partly working in my local copy.

if it helps portability, I can remove the gda dependencies in favour of a 
direct postgres connection using libpq, as the planned way using gda won't 
work anyway...
