fulmar, magpie and treepie are unhappy after this commit, and all of
them have the same complaint related to the order consistency of
partitions showing up in psql:

    Partition key: LIST (a)
-Partitions: part_1 FOR VALUES IN (1),
+Partitions: part_null FOR VALUES IN (NULL),
+            part_1 FOR VALUES IN (1),
             part_2 FOR VALUES IN (2),
-            part_3 FOR VALUES IN (3),
-            part_null FOR VALUES IN (NULL)
+            part_3 FOR VALUES IN (3)
