Does anyone know if pgsql hstore would facilitate something like XAPI with similar performance, but allow multiple parameters?
The performance will be highly dependent on the number of queries but I think it will be in a similar range. One ting to remeber is, that osm2pgsql does *not* store junction information, just simple geometries. This makes it suitable for most display purposes but eg. not usable for routing. That's also the reason why you can't generate .osm format from osm2pgsql databases without the (possible slow) access to the _node, _way or _relation tables.
