Check the index with:

  sqlite3 db/rep-cache.db "pragma integrity_check"

Compare the ordered list:

  sqlite3 db/rep-cache.db "select hash,revision from rep_cache order by revision"

with the 1.8 list and you may be able to identify which revisions are
missing from the 1.9 rep-cache.  There isn't any way to fix the missing
deduplication other than a dump/load, but it would be interesting to
find out why it failed.  Which method did you use to write during sync:
file, svn or http?
