Is there any reason that this doesn't exist as a standalone library? I 
could see there would be scope for a shared address parser, and perhaps 
even a wrapper CLI that takes an address string on stdin and outputs a 
set of coordinates on stdout. Or are the lookups done using native 
PostgreSQL tools such as full text search?

ATB,
