[OSM-dev] Which OSM to PostGreSQL converter shall I use?

Hello,

I need a postgresql database to do following jobs:
1. A lot of shortest path tree constructions given an root node.
2. A huge amount of queries for length of roads. ( any suggestion for
converting the coordinates to Cartesian system?)
3. A few queries for nearby nodes given a point.

Actually, I need these jobs for my map matching application.

I tried to use osm2pgsql to generate a database. But it seems not
simple/efficient to accomplish job 1. I haven't tried others. And I hope
that I can get some useful information here.

Thank you in advance!

Best regards.

Jingmin
