Sometimes I have to solve the result types of some query. It is invisible
in psql. You have to materialize table or you have to create view. Now,
when we can enhance \g command, we can introduce query describing

some like

select a, b from foo

     |   type     | length | collation | ....
 a  | varchar  |     30  |
 b  | numeric |      20 |

What do you think about this idea?
