In principle we don't need a catversion bump here, since there's
no C-code-versus-catalogs compatibility issue.  But we have usually
done one for information_schema changes.

I think I'd vote against back-patching.  The fact that this went
unnoticed for 14 years demonstrates what low impact it has.
I don't foresee people wanting to manually replace that view in
order to fix it in existing installations.
