The `Case` constraint is used for functions like `bool`, `case_`, `maybeTable`, `nullable`, all of which ultimately compile down to a PostgreSQL `CASE` statement. `Case` has two instances: an overlapping `Table Expr a => Case a` instance, and a `Case b => Case (a -> b)` instance, that allows expressions like `maybeTable id (+)` which would not have been possible for.
