    The method contract here is confusing to me: is this supposed to introduce an additional
layer of quotes? I find it confusing to couple both the responsibilities of quoting identifiers
and parsing table names from a schema-qualified name.
    I'd prefer to have this return just the table name, unquoted, and leave it up to later
components to escape it. If you _do_ think we should do quoting here, please explain that
part of the API contract in the Scaladoc.
