How to UPDATE in ROW-style?

Hello.

How could I write something like:

DECLARE r table%RWTYPE;

UPDATE table SET (table.*) = (SELECT r.*) WHERE id = r.id;

*This *syntax is invalid, and I cannot find another proper way to do it
without explicit enumeration of table's columns.

I don't want to explicitly specify table's column to minimize later
refactoring.



P.S.

The corresponding INSERT operator works fine:

DECLARE r table%RWTYPE;

INSERT INT table (SELECT r.*);

Please say if a similar syntax for UPDATE exists.
