Michael Paquier	4f1882b960	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 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.

Michael Paquier	e643a315fc	Tweak regression test of pg_walinspect to be less collation-sensitive ... \dx was used on pg_walinspect to list its objects in 1.0 but the names of the objects in this version do not have an order that is always guaranteed depending on the collation used. Rather than append a COLLATE clause in the query of \dx, this tweaks the regression test to produce an output whose order is guaranteed.

Michael Paquier	5c1b662807	Rework design of functions in pg_walinspect ... This commit reworks a bit the set-returning functions of pg_walinspect, making them more flexible regarding their end LSN: - pg_get_wal_records_info() - pg_get_wal_stats() - pg_get_wal_block_info() The end LSNs given to these functions is now handled so as a value higher than the current LSN of the cluster (insert LSN for a primary, or replay LSN for a standby) does not raise an error, giving more flexibility to monitoring queries. Instead, the functions return results up to the current LSN, as found at the beginning of each function call. As an effect of that, pg_get_wal_records_info_till_end_of_wal() and pg_get_wal_stats_till_end_of_wal() are now removed from 1.1, as the existing, equivalent functions are able to offer the same possibilities.

Michael Paquier	1f282c24e4	Refactor and improve tests of pg_walinspect ... The regression tests of pg_walinspect are reworked on a few aspects: - Reorganization on the validation checks done for the start and end LSNs on the six SQL functions currently available in 1.1. - Addition of a few patterns doing bound checks for invalid start LSN, invalid end LSN, and failures in reading LSN positions, for anything that's been missing. - Use of a consistent style across the whole, limiting blank lines across the queries. - Addition of a new test script for upgrades. For the time being, this is straight-forward with a check that the upgrade from 1.0 works correctly. This will be made more complicated once the interface of this extension is reworked in 1.1 with a follow-up patch. Most of the contents of this commit are extracted from a larger patch by the same author, largely reorganized by me to minimize the differences with the upcoming work aimed to lift the bound checks on the input LSNs used by the functions of this extension.
