Thanks for adding the diffs spaetz.

For reference, multiple planetdiff tools can be persuaded to pipeline
together. This allows you to load latest planet.osm into osm2pgsql using
an old dump + multiple diffs as follows:

$ planetpatch planet-070718.osm.bz2 planet-070718-070725.diff.xml.bz2 | \
  planetpatch /dev/stdin planet-070725-070801.diff.xml.bz2 | \
  planetpatch /dev/stdin planet-070801-070808.diff.xml.bz2 | \
  osm2pgsql -
