Maybe mine is an impossible suggestion, or maybe is just plain
stupid... but would be possible to create a "supershema" os sorts,
shared by all databases?
basically, a schema that is stored by default on all the databases,
with a backend process that takes care of the replication.

I insist, mine is just a wild suggestion, or just downright stupid...
