I think zope/rdb tries to be as general as possible, so using
DatabaseException for all RDBMS errors may be sometimes desirable
especially if someone builds application that
shouldn't be bound to one, specific database adapter. But I think it
is rather rare(?) situation, and there are still generic errors
like cx_oracle.Error or psycopg.Error. They're DBMS aware but
it shouldnt be hard to write a common handler or something like
that if someone has to just handle all DBMS errors at once.

Current implementation may cause some problems if someone needs real
errors standarized by python dbapi.
For me it would be cleaner to just have standard dbapi errors in Zope.
