The PG wire protocol specification [1] defines these fields thus:

        If the field can be identified as a column of a specific
        table, the object ID of the table; otherwise zero.

        table, the attribute number of the column; otherwise zero.

My reading of that is that we should populate these fields only for
the case of direct selection from a table.

s/can be identified as/is/g  ?

Experience shows people are inferring a lot from "can be identified" so we should remove it.  "is" maybe over-simplifies a bit but in the correct direction.
