Everything is a scalar value now, and while this does involve more
boilerplate it will also catch type conversion issues like
"1" + 0 === "10" in the future.
This is in preparation for a transition to SQLite. SQLite does have
a similar concept called "attached databases", but it's kind of a
pain to deal with if you're casually browsing a database from the
`sqlite3` CLI so we'll just use some slightly uglier explicitly
namespaced table name identifiers instead.
