Hello, I just commited a patch for osm2pgsl for optional generation of a hstore column (hstore new).
For those of you who don't know about hstore colums yet: Hstore is for sets of key/value pairs. As associative array datatype, just like a hash in perl or dictionary in python. This should come in handy especialy for rarely used tags. Using hstore one can use any tag in sql queries like this: gis=> select count(*) FROM planet_osm_point where ((tags->'man_made') = 'tower'); count ------- 447 (1 Zeile) Indexes can be added to hstores as well. Currently the patch has not been tested in conjunction with incemental database updates.
