Oops. Minor change. Last two fields are updated by rules.

Nothing special, just some 'fake' fields and no join (mainly there for
access control and compatibility across several applications):

 SELECT
    brokenTable.id,
    brokenTable.someField1 AS someAlias1,
    brokenTable."someField2"::character varying(64) AS someAlias2,
    0::bigint AS someAlias3,
    brokenTable.someField4,
    'crypt'::character varying AS someAlias5,
    brokenTable.fieldUpdatedByRule1,
    brokenTable.fieldUpdatedByRule2
   FROM brokenTable;
