Well, the thing is, we've pretty much had it handed to us that
current-command indicators that aren't up to date are not very useful.
So rate-limited updates strike me as a useless compromise. We have
the "real" solution (status advertised in PG's shared memory) already,
so the question in my mind is just how fast DBAs will wish to transition
to looking at "select * from pg_stat_activity" instead of looking at
I don't see anything wrong at all with making update_process_title
default to "off" in BSD-specific packaging of Postgres. It's a harder
sell to turn it off by default everywhere, because of all them Linux
users for whom that's just taking away a convenient status viewing
method. I think we might get there eventually, but we need a decent
interval to wean people away from the old method.
[ Disclaimer: I work for Red Hat, so am unlikely to favor doing anything
that is a loss on Linux. But I do use and like other platforms too;
just don't happen to have any BSD in-house currently, unless you're
willing to count Darwin as BSD. ]
