This stores the UDFs in the database. Which means each database can have its own UDFs.

This makes more sense if you're someone who hosts the databases of others, but I it's still interesting otherwise.

Like, if something like that was included in the CLI, one of the many browser apps, or the online playgrounds, your DBs could carry their own UDFs portably within themselves.

It'd be even more interesting if it supported virtual tables as well.
