geometry processing not consistent when using --hstore ?

[etienneJr]

Hi!
I'm using osm2pgsql (v1.11 or 2.0) with either -hstore or --hstore-all to get all the geometries of all the OSM elements.
If an element has a tag listed in my .style file, geometry processing is fine as usual: a way is added to the _line or _polygon table depending on its shape.
But I noticed a different behaviour for elements without any of the listed tags (added because of the --hstore option) : all the ways are added in the _line table whether they are closed or not.
It this behaviour expected ? Or is it a bug and all the geometries should be processed the same way for all the elements ?
Thanks!

What is your command line?

This is expected behaviour. The .style file is telling osm2pgsql which tags are treated as linear or polygon (in the "Flags") column. The default is linear, so if you don't have something in your style file it is linear.

Note that the old output using the style file is deprecated. Please switch to using the more modern "flex" ouput, there you have much more flexible options telling osm2pgsql what to do with which tags.

OK thank you, the flex output does indeed look incredibly flexible and powerful, I'm going to make the effort to understand how it works, I've seen that there are lots of examples proposed, that's great!
