Yes, applying this patch will not cause the 'rules' test to fail.
Even if the pg_stat_activity view definition information in system_views.sql is capitalized (inconsistency is fixed) by this patch, it will be lowercase when this view is installed in database. So, the test result does not change.
Just to be sure, I ran the 'make check' and 'make check-world', and I confirmed that all tests were passed.
