Except for the "import xxx" line, they should all be identical. Think
about it: the backend is what varies. All adapter code for PostgreSQL
should form the exact same strings quoted the exact same way, should
escape the exact same characters in the exact same way, should call the
exact same code to begin/commit/rollback transactions, etc. The only
thing that should change is the name of the library to import.

Yes, it does complicate things, because you're now programming to the
exception. 99.9% of all Dabo users will be able to use the standard
libs. Those few who want to do something different can take care of the
tiny effort involved in renaming the file, or simply changing the
single import line of the existing file. And once we get out of this
early alpha stuff, this stuff isn't going to be changing very often, if
at all, so it's not like this will be a weekly chore.
