The change of hash function with hashable-1.3.1.0 changes object ordering in JSON output, causing some test failures: https://app.circleci.com/pipelines/github/PostgREST/postgrest/805/workflows/067844c9-9ce4-49e8-8790-315625ab309b/jobs/8309 e.g.: > expected: "[{\"b\":\"baz\",\"a\":\"bar\"}]" > but got: "[{\"a\":\"bar\",\"b\":\"baz\"}]" This changes the tests to not compare against the body literally, and instead use the ResponseMatcher instance from Test.Hspec.Wai.JSON.
