Support for other database types

[timwis]

Hey, really awesome job on this project! A few months ago I started working on the same idea with dataface. I didn't get as far as you did, and frankly I'm glad this came out so that I don't need to! One feature I was excited about, though, was support for multiple database types, primarily leveraging knex.js for query building. Knex doesn't quite do everything, but my plan was to use basic class inheritance to write DB-specific queries for things that knex didn't support. Here's what I mean.

Any thoughts about supporting more database types?

We are planning to include MySQL and MariaDB support in future. Thanks for your advice on knex.js
