[Tile-serving] [osm2pgsql] Huge performance loss when using --extra-atributes (#189)

[Benjamin Börngen-Schmidt]

Okay then how about first using the tags to consider if the Object should be added and after that add the extra_attributes as tags?

https://github.com/openstreetmap/osm2pgsql/blob/master/parse-pbf.c#L253 adds the extra_attributes to the tags
https://github.com/openstreetmap/osm2pgsql/blob/master/parse-pbf.c#L257 adds all the tag tags to tags
https://github.com/openstreetmap/osm2pgsql/blob/master/parse-pbf.c#L266 checks if we want the node

So placing L253 after the want node check would only add the extra attributes if the node is wanted
