Well, we can talk about it, but I still think that any frontend that
relies on such information is broken by design. (And if that means the
JDBC spec is broken, then the JDBC spec is broken.)
Just to start with, if I do "SELECT * FROM view", am I going to see the
info associated with the view column, or with the hypothetical
underlying table column? (Actually, didn't I already make a list of a
bunch of ways in which this concept is underspecified? AFAIR, you
didn't suggest answers to any of those questions ... but we need answers
to all of them if we are going to implement the feature.)
