[OSM-dev] The evolution of the osm2pgsql style file

There's a still a lot of hardcoded knowledge built into osm2pgsql and
it is in some respects rather inflexible. To that end I would like to
extend osm2pgsql at least in the following ways:

- The output tables specified by the style file also, so that it would
be easy to, for example, create a table with all the railway stuff or
with just waterway tags.
- Include in the style file information about tag values, to control
where it gets stored.
- Information like z_order and roads will then also be specified by
the style file.

My proposed syntax is something like below. Any comments?

>tablename  means that tag will activate writing to that table.

Have a nice day,
