Improve a bit the tests of pg_walinspect
This commit improves the tests of pg_walinspect on a few things:- Remove aggregates for queries that should fail. If the code isreworked 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 scansacross ranges, rather than zero records.- Adjust a few comments, for consistency.Author: Bharath RupireddyDiscussion:https://postgr.es/m/CALj2ACVaoXW3nJD9zq8E66BEf-phgJfFcKRVJq9GXkuX0b3ULQ@mail.gmail.com
