Thanks, Tom.

I tested your patch against the current master branch 78aa616b on
MacOS Catalina. I have nothing to add to the patch.

Yep, that's unfortunate. I see several tests for `AT TIME ZONE`
syntax, which is a syntax sugar to timezone() with timestamp[tz]
arguments. But considering how `timetz` type is broken in the first
place [1], I'm not surprised few people feel motivated to do anything
related to it. Do you think there is a possibility that one day we may
be brave enough to get rid of this type?
