new idea for COPY and MOVE

hi
what do you tink about :
COPY [ namespace1. ] table [ STRUCT ONLY ] TO [namespace2.] table2;
MOVE [ namepsace1. ] table TO [namespace2.] table2;

and this same whit types, functions etc

and :

ALERT FUNCTION func (ARGS) SET OWNER new_owner;

and :

CREATE TYPE new_type AS table;

this can by replaced by LIKE : CREATE TYPE new_type AS ( LIKE table )
what i saw in one mail on this maillist

can be ?

bye
