An interesting twist to this is that if you write your system to use
PostgreSQL as the backend, you quickly start taking advantage of all the
cool features that PostgreSQL has. This makes your coding easier, and your
life easier, but badly breaks any compatibility with any other database.
In my experience, it's easy to convert MySQL apps to run under Postgres --
it's very difficult to convert Postgres apps to MySQL, because MySQL just
doesn't have the required features.
