Looks like you have some tests to update:

force-indexes
        check force-index adds indexes:                                          FAIL (51.21s)
          test/Test/Cardano/Db/Mock/Validate.hs:153:
          unexpected number of indexes: got 171 expected 172
          Use -p '/Conway unit tests.Command Line Arguments.force-indexes.check force-index adds indexes/' to rerun this test only.
        check no force-index doesn't add indexes:                                FAIL (51.22s)
          test/Test/Cardano/Db/Mock/Validate.hs:153:
          unexpected number of indexes: got 108 expected 107
          Use -p '/Conway unit tests.Command Line Arguments.force-indexes.check no force-index doesn'\''t add indexes/' to rerun this test only.
