I think we didn't set up the infrastructure to VACUUM the database. The default in sqlite is not to VACUUM ever, so we probably should either stop the entire thing and vacuum it once a week or we could set up autovacuum to incremental or full (the latter would vacuum at each commit) if we ever ran out of space.
