Absence of evidence is not evidence of absence, unfortunately.
In other words, the fact that "make check" passes may easily be just due
to an omission in the regression tests. Apparently there's no test that
we actually produce the error when the type can't be inferred.
That being said, I don't know if this is a correct change or not.
Perhaps it is, perhaps it isn't - not sure. Consider adding it to the
next commitfest [https://commitfest.postgresql.org/15/] where you'll get
more feedback. You'll need to submit it to pgsql-hackers though.
