If at all possible, I'd prefer we steer clear of non-free databases, but
I'd prefer anything other than MySQL.

MySQL is often held up as a great thing by people who need a database
and had never seen one before. If you've never used a relational
database before, then, yes, MySQL is better than not using a relational
Database. Unfortunately, if you've used other relational databases,
MySQL is crap.

For example, it's taught open source people that you can't rely on
database referential integrity, you have to program that in your front
end (rails, for example).

It's taught people that sub-queries are a bad thing because they are
slower than doing a weird impossible to read join statement:

Other open source databases I know (Postgres and Firebird) aren't like that.
