This looks like an application kind of fix, not a library solution.  A
JDBC driver can't go around creating tables and triggers and other things.

It might be worthwhile to investigate how other JDBC drivers handle this.  
So far I've only looked at MySQL, but checking MaxDB and Firebird's driver 
source would be revealing.  Checking commercial drivers would be good too, 
but I'm not sure how legal that is.
