EXECUTE of a SELECT ... INTO now draws a 'not implemented' error,
rather than executing the INTO clause with non-plpgsql semanticsas it was doing for the last few weeks/months. This keeps our optionsopen for making it do the right plpgsql-ish thing in future withoutcreating a backwards compatibility problem. There is no loss offunctionality since people can get the same behavior with CREATE TABLE AS.
