I use osm2pgsql to load osm.pbf Data into a PostGIS database.
One objective is to store the osm_timestamp into a column. The flag "-x" is used in the cmd code. With the following line in the mapfeatures.style, the osm_timestamp is recognized:
node,way osm_timestamp timestamptz(0) linear
This results in a column "osm_timestamp", but all lines are "NULL".
I can't find a solution, because everything but NULL is expected.
