Inheriting text[] field

Dear Friend,

I have the following problem when I try to inherits one table with
text[] field into another.
I am useing PostgreSQL 7.2.3.
I suppose that this is a BUG but I am not sure.
Any ides.
10x in advance.

test_libvar=# create table temp_a(
test_libvar(# name text[]
test_libvar(# );
CREATE
test_libvar=# create table temp( name text[] ) inherits (temp_a);
NOTICE: CREATE TABLE: merging attribute "name" with inherited definition
ERROR: CREATE TABLE: attribute "name" type conflict (_text and text)

P.S. I know that I can avoid this by scipping the 'name' field into the
second table but what if I need to set some CONSTRAINTS to it.
