The salient reason is that the spec only defines width_bucket for numeric
input arguments, whereas stuff like max/min is defined *by the spec* for
other data types.

Since there's no spec-based argument for allowing width_bucket for other
datatypes, and only an (IMHO) very weak use-case for it, I don't think
we should add the clutter.

       choose an index scan if your joining column's datatypes do not
       match
