v9.5/9.6

create these objects -
CREATE TABLE constraint_rename_test (a int CONSTRAINT con1 CHECK (a > 
0), b int, c int);
CREATE TABLE constraint_rename_test2 (a int CONSTRAINT con1 CHECK (a > 
0), d int) INHERITS (constraint_rename_test);
ALTER TABLE constraint_rename_test ADD CONSTRAINT con3 PRIMARY KEY (a);

v9.6/v10 - run pg_upgrade

pg_restore: creating COMMENT "SCHEMA "public""
pg_restore: creating TABLE "public.constraint_rename_test"
pg_restore: creating TABLE "public.constraint_rename_test2"
pg_restore: [archiver (db)] Error while PROCESSING TOC:
pg_restore: [archiver (db)] Error from TOC entry 351; 1259 16388 TABLE 
constraint_rename_test2 edb
pg_restore: [archiver (db)] could not execute query: ERROR:  column "a" 
in child table must be marked NOT NULL
     Command was:
-- For binary upgrade, must preserve pg_type oid
SELECT 
pg_catalog.binary_upgrade_set_next_pg_type_oid('16390'::pg_catalog.oid);

manually i am able to create all these objects .
