No need to do that if dump/loading.

Truncating the rep-cache is necessary if you backdate db/current.
Running 'svnadmin recover' will do it for you if you use 1.7 but not if
you use 1.6. For 1.6 use the sqlite3 command or simply delete
db/rep-cache.db.
The other thing that can go wrong if you truncate a repository is that
you may end up with orphan exclusive locks (locks on files that don't
exist). This will prevent you adding those files in future until you
unlock the path. This is unlikely to affect an svnsync mirror since you
probably don't lock files in the mirror.
