Maybe for this specific use case it's easier to teach psql how to do that,
instead of trying to amend the SQL implementation? Example:

SELECT * \- col1 \- col2 FROM table

psql looks up the columns, translates * into the actual list minus these two
columns and lets you continue entering the query.
