You know, rather than adding new columns to pg_class, why not extend
the stats collector to collect this information. This seems to fall
well within its mandate and it already has the necessary infrastructure
to store info like this. The people likely to want this sort of info
are likely to be running the stats collector anyway. The GUC then
becomes.
stats_autovacuum= on
No more fiddling with log levels or parsing log file, just:
select <the info you want> from pg_stats_autovacuum;
If this table is empty, it isn't running. How often do you want to know
if it was running 5 hours ago?
Thoughts?
