// ObjectLabels must resolve against a real database. A pure unit test cannot
// catch encoding-level failures: pgtype.Array without explicit Dims encoded as
// an empty array, so the query ran fine and returned nothing — green tests,
// dead feature. This hits a throwaway database like the rest of this package.
