pg data type of osm_timestamp colum is text but not timestamp(0)

[thbeutin]

after adding the required line to the style file and importing OSM data with --extra-attributes the tables planet_osm_point, _line and _polygon cotains the column osm_timestamp, but unfortunately the datatype is text. I'd like to have a standard (p)sql data type timestamp(0) for space and usage reasons - is this possible?

Ok, this was a sloppy investigation on my side - if i use a line like:
"node,way osm_timestamp timestamp(0)"
in the style i get the timestamp as a correct (postgre)sql value.
but this seems not to work if i use pbf input data - i'll open a separate issue on this.
