Which DB engine are you using?.
My statement seems to hold true for sqlite, the table still has the
old fields, I can execute select statements using them, it might be a
bug then. I will test with the latest trunk.

What I need to find out is which dbs are defined, e.g. in models:
dbX=SQLDB(...)
dbY=SQLDB(...)
then it would be [dbX, dbY] or even better {'dbX':dbX, 'dbY':dbY}

Maybe using getattr over the locals() or globals()? but I can't figure
it out yet...
