something like:
- clean _all_ your refs to SA stuff like tables, mappers etc
- sqlalchemy.orm.clear_mappers()
- metadata.drop_all()
- dbengine.dispose()
plus eventualy
del x._instance_key
del x._state
for all instances that are still around, and u want them resued in
another db/mapping/...
plus each db-dialect has its own way of removing/recreating a db (e.g.
delete the file for sqlite, or dropdb xxx fos postgres etc).
see dbcook.usage.sa_manager (methods destroy() and
detach_instances() ) and dbcook.usage.sa_engine_defs, various
recreate()s
