CREATE TABLE ... LIKE ... should mark the columns it creates with

attislocal = true, since they are not really inherited but merely copied
from the original table.  I'm not sure if there are any cases where it makes
a real difference given the existing uses of the flag, but wrong is wrong.
This was fixed in passing in HEAD by the LIKE INCLUDING CONSTRAINTS patch,
but never back-patched.
