This commit improves the tests of pg_walinspect on a few things: - Remove aggregates for queries that should fail. If the code is reworked in such a way that the behavior of these queries is changed, we would get more input from them, written this way. - Expect at least one record reported in the valid queries doing scans across ranges, rather than zero records. - Adjust a few comments, for consistency.
