I've wanted this feature lots of times and would be delighted to see it in Postgres.

I take the proposal to mean this: SELECT listOfColumns [EXCEPT listOfColumns] FROM ... not this: SELECT listOfColumns [EXCEPT (listOfColumns) [listOfColumns [EXCEPT (listOfColumns)]]]... FROM ... So there is always a single EXCEPT clause (if any) and it comes after the entire SELECT clause. Then there is no ambiguity. Also this approach makes the feature easy to understand and use. I don't see any benefit to letting people interleave selected & excepted columns. Regards, Paul
