[Tile-serving] [osm2pgsql] Figure out a way to use fastupdate on indexes (#37)

[pnorman]

fastupdate does not work with osm2pgsql because with a high work_mem it builds up a large temporary part of the index it has to sequentially scan, slowing down updates significantly

It would be nice if we could use fastupdate with a smaller temporary part of the index.
