'create script' not usable for columns set 'not null' and 'default'

In pgAdmin III v.1.14.1, if you navigate to 
schemas/public/tables/<table>/Columns/<column> and right-click on the column 
name and press "create script", you often get a script that will not execute.

The problem occurs when you have a column that has "NOT NULL" and a "DEFAULT" 
property.

e.g. A script generated by pgadmin might be as follows:
> -- Column: waged
>
> -- ALTER TABLE custom_ccowa_kwc DROP COLUMN waged;
>
> ALTER TABLE custom_ccowa_kwc ADD COLUMN waged2 integer;
> ALTER TABLE custom_ccowa_kwc ALTER COLUMN waged2 SET NOT NULL;
> ALTER TABLE custom_ccowa_kwc ALTER COLUMN waged2 SET DEFAULT 1;

But if you delete that column and insert the above text into the SQL editor 
and press "Execute query". then you get the following error message:

> ERROR:  column "waged2" contains null values
>
>
> ********** Error **********
>
> ERROR: column "waged2" contains null values
> SQL state: 23502

Could pgAdmin please be modified to generate a script like this instead:
> ALTER TABLE custom_ccowa_kwc ADD COLUMN waged2 integer NOT NULL DEFAULT 1;

Thanks for considering this, I couldn't find a similar bug report in the archives.
