Review comment:
Firstly, thank you for keeping working on this, @walterddr!
Comment of this line:
As the expression is written as `myColumn.func(...)`, shouldn't it be parsed
to a DOT expression? But by looking into the generated parse tree I think the
result is more like a `schema.func(...)` (see following).
