In function ATExecDropConstraint(), for the constarint "test_constraints_val1_val2_key" con->connoinherit is false, due to which it tries to drop the constrint from child table as well. I have checked that from function index_constraint_create() when it calls function CreateConstraintEntry(), the flag for noinherit passed is false. I think this is the reason of failure for the same.
