just quickly note the not good error message before you rebase.

src7=# create domain d_fail as int4 constraint cc GENERATED ALWAYS AS (2) ;
ERROR:  unrecognized constraint subtype: 4
src7=# create domain d_fail as int4 constraint cc GENERATED ALWAYS AS
(2) stored;
ERROR:  unrecognized constraint subtype: 4
src7=# create domain d_fail as int4 constraint cc GENERATED ALWAYS AS
(2) virtual;
ERROR:  unrecognized constraint subtype: 4

reading gram.y, typedef struct Constraint seems cannot distinguish, we
are creating a domain or create table.
I cannot found a way to error out in gram.y.
