So, about that cast-to-typmod-minus-one business - Mailing list pgsql-hackers

We had left it as an open issue whether or not to risk back-patching
5c056b0c2 into stable branches [1].  While updating the v14 release notes,
I realized that we can't put off that decision any longer, because we
have to decide now whether to document that as a new behavior in v14.

I'm inclined to back-patch, since nobody has complained about this
in 14beta3.  Thoughts?

            regards, tom lane
