I saw something about this on IRC (#zco) the other day, and just
confirmed.

Apparently you can use svndumpfilter to compress the revisions (and if
necessary change paths) in the fdopostgis repository, and then when you
import it it just adds new revisions for each change.

I can't say that I totally understood it, but we can test it thoroughly
first with a dump/restore on a different server using the OSGeo svn
snapshots.
