Splitting thee database may not be a good idea. Especially if you care
about backup and expect databases to be globally consistent (not just
per-database consistent) after a restore.
I wrote a daemon to overcome this problem by tracking which
transactions are committing to try to find points at which
databases are globally consistent. It does its job so far, but
beware: it won't resist malicious usage (trivial to DoS).
