The big advantage in standardising on a single RDBMS is better
integration. With firebird (and postgres) you can have stored procedures
and triggers that fire off events to which callbacks can be attached to
in your code - that way you get two way interaction. You cant abstract
that so if we allow multiple DB's we lose this essential and highly
desirable functionality (they all use different syntax for stored procs
so abstraction is a non starter here).
