Same as #33230 (comment). I wouldn't backport either. |

What changes were proposed in this pull request?
PR #15764 disabled creating permanent views based on temporary views or UDFs. But AlterViewCommand didn't block temporary objects.
Why are the changes needed?
More robust view canonicalization.
Does this PR introduce any user-facing change?
Yes, now if you alter a permanent view based on temporary views or UDFs, the operation will fail.
How was this patch tested?
Add new unit tests.
