Re: remaining sql/json patches

Hi! another minor issue I found:

+SELECT pg_get_expr(adbin, adrelid)
+FROM pg_attrdef
+WHERE adrelid = 'test_jsonb_constraints'::regclass
+ORDER BY 1;
+
+SELECT pg_get_expr(adbin, adrelid) FROM pg_attrdef WHERE adrelid =
'test_jsonb_constraints'::regclass;

I think these two queries are the same? Why do we test it twice.....
