We could dodge that case by only changing the behavior when showstar is
false; there is no need to change it otherwise.  The patch has assorted
other bugs too, in particular its schema-name treatment seems completely
wrong (hint: RelationIsVisible is not the same as TypeIsVisible, and
it's at best shaky to assume that a relation's name is the same as its
rowtype's name anyway).

More generally, it seems rather inelegant to be forcibly adding a cast
when in most cases the existing notation is not wrong.  AFAICS the
plain "relname" notation is only ambiguous if there is a column of the
same name as the relation.  I wonder whether we should instead address
this by not letting the parser strip the "no op" cast in the first
place.

You mean that the parser should not strip the "no op" cast in all cases or in the case only when the parser somehow detects a column of the same name as the relation?
