Review comment:
Yeah, I think that the problem is that ```catalog.`file://path/to/table`
``` is ambiguous and should not be supported. But parsing it successfully means
that it would be translated to a path-based table with a catalog.
I don't think a more complicated check is needed, to see if the `/` is
probably escaped. If there is a `/`, then it's a path. That's a really simple
rule to follow.
