We could fix this by implementing a relatively simple abstraction
layer ourselves, couldn't we?  We could provide a translation
list for each supported backend driver.   Yes, it would still mean
that we'd need to extend the list to support new DBI backends,
but it should at least limit the support requirements to a small
location where the DB-specific translations get done.
