Now that 0003 is committed as d75288fb27, and 33394ee6f2 conflicts
with old 0004, I'd like to post a rebased version for future work.

The commit 33394ee6f2 adds on-exit forced write of WAL stats on
walwriter and in this patch that part would appear to have been
removed. However, this patchset already does that by calling to
pgstat_report_stat from pgstat_beshutdown_hook.

regards.
