Hi Daniel,

Despite it's a pretty old thread regarding feeding OSRM with postgis
geometries, I have new lights to bring up

I find this a bit restrictive and I wonder why it's valuable to stuck osrm
on osm data only.
I work for a company which is interested to use osrm as a router for public
works (not cycling nor car or whatever).
We have lot of private data we process into a postgresql db in which osm
data is also imported.

OSM XML file production at the end of our process generate a lot of
overhead as to feed osrm.
This doesn't bring advantage at all.

We think about creating another connector which would enable osrm-extract
to get its data directly for pgsql.
Currently we're not aware of how deep the xml/libosmium is linked to
osrm-extract binary.

Our use cases enlarge the potential and relevance of osrm in
industrial/profesionnal use.
We look to be as constructive as possible and it will be a pleasure to
share since osrm is great tool.

All the best
