Since a051e71e28a1, pg_stat_io is able to track statistics for the WAL activity, providing an equivalent of pg_stat_wal with more granularity for the fsyncs/writes counts and timings, as the data is split across backend types. This commit now recommends pg_stat_io rather than pg_stat_wal in the section "WAL configuration", some of the latter's attributes being candidate for removal in a follow-up commit. Extracted from a larger patch by the same author. Author: Bertrand Drouvot <bertranddrouvot.pg@gmail.com> Discussion: https://postgr.es/m/Z7RkQ0EfYaqqjgz/@ip-10-97-1-34.eu-west-3.compute.internal
