The first stage of the coastline checker tool chain is a modified copy 
of an old revision of osm2pgsql. It could be adapted for pbf, same as 
the current osm2pgsql. It does two passes over the data, that's why a 
simple pbf2osm pipe doesn't work.

The rest of the tool chain works on the resulting interim files, and 
wouldn't need to be adapted for a pbf planet.

16GB should be plenty. Last year I could still do a complete coastline 
run with a 4GB server, and it probably needs less than that.
