Postgres database on cloud drive like dropbox

[Bangwhiz]

Will this work, or would it be just to darn slow?

Since Dropbox actually keeps the files on your computer the actual reads and writes to the database shouldn't be slow, although you may get some performance degradation as the changes are synced, because the hard drive is being used by another process meaning that PostgreSQL may have to wait from time to time.
