I have remove this TODO item:

        * %Add pg_get_acldef(), pg_get_typedefault(), pg_get_attrdef(),
          pg_get_tabledef(), pg_get_domaindef(), pg_get_functiondef()
        
          These would be for application use, not for use by pg_dump.

Seems there is lack of interest in adding this feature because of
maintanance concerns.

The attached patch is rejected for the same reason.  Sorry for the
confusion.
