Are you sure that LIKE is not _supposed_ to be inheritable. I mean that
changes done to the LIKE table should carry over to the table defined
create table template( i int);
create table instance(like template, t text);
alter table template add column j int;
and now instance should have columns i,j,t .

Would this not detach the definitions .
