Michael Paquier 3f1db99bfa Handle auxiliary processes in SQL functions of backend statistics ... This commit impacts the following SQL functions, authorizing the access to the PGPROC entries of auxiliary processes when attempting to fetch or reset backend-level pgstats entries: - pg_stat_reset_backend_stats() - pg_stat_get_backend_io() This is relevant since a051e71e28 for at least the WAL summarizer, WAL receiver and WAL writer processes, that has changed the backend statistics to authorize these three following the addition of WAL I/O statistics in pg_stat_io and backend statistics. The code is more flexible with future changes written this way, adapting automatically to any updates done in pgstat_tracks_backend_bktype(). While on it, pgstat_report_wal() gains a call to pgstat_flush_backend(), making sure that backend I/O statistics are updated when calling this routine. This makes the statistics report correctly for the WAL writer. WAL receiver and WAL summarizer do not call pgstat_report_wal() yet (spoiler: both should). It should be possible to lift some of the existing restrictions for other auxiliary processes, as well, but this is left as future work.
