[ scratches head... ]  When I do that, it refuses to insert into t2
either:

regression=# create table t1(a integer not null, b integer);
CREATE TABLE
regression=# create table t2(a integer, b integer) inherits (t1);
NOTICE:  merging column "a" with inherited definition
NOTICE:  merging column "b" with inherited definition
CREATE TABLE
regression=# insert into t1(a,b) values(null,1);
ERROR:  null value in column "a" violates not-null constraint
DETAIL:  Failing row contains (null, 1).
regression=# insert into t2(a,b) values(null,1);
ERROR:  null value in column "a" violates not-null constraint
DETAIL:  Failing row contains (null, 1).

This is the behavior I would expect, and I see it in all active
branches.  Have you modified the code around column inheritance?
