We really ought to make that a hard error. And ideally fix things so
that the type of the view column will be resolved as text, so that you
don't hit this condition in the first place; but there is no good that
comes out of allowing a view to be created like this.

This is a seriously ugly kluge that's attacking the symptom not the
problem. Or really, a symptom not the problem. There are lots of
other symptoms, for instance
regression=# select * from v order by 1;
ERROR: failed to find conversion function from unknown to text
