Daniel Gustafsson d959523257 Disallow NULLS NOT DISTINCT indexes for primary keys 
A unique index which is created with non-distinct NULLS cannot be
used for backing a primary key constraint.  Make sure to disallow
such table alterations and teach pg_dump to drop the non-distinct
NULLS clause on indexes where this has been set.
