doc: Recommend pg_stat_io rather than pg_stat_wal in WAL configuration 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.
