Jeff asked me if imposm supports Windows. I'm not sure if everyone was aware of it, but it only runs on unix systems, because one library is not available on Windows. Imposm can import from the Linux host to a PostGIS on the Windows host, though.
Don't know if that does change anyone's mind.

For the DB schema:
Here is a list of all tables that imposm creates by default:
http://imposm.org/docs/imposm/latest/database_schema.html

Here is the configuration of the default mapping:
https://bitbucket.org/olt/imposm/src/tip/imposm/defaultmapping.py
You can see which OSM tags are included in which table.
I'll post a complete PostgreSQL schema in the wiki.

Regards,
Oliver
