Why do we want commits/rollbacks counted if we only have command string
enabled?  Here is the test:

    if (pgStatSock < 0 ||
        !(pgstat_collect_querystring ||
          pgstat_collect_tuplelevel ||

and here are the functions that have it where I think it is wrong:


The stats_command_string documention makes no mention of this:

        Enables the collection of statistics on the currently
        executing command of each session, along with the time at
        which that command began execution. This option is off by
        default. Note that even when enabled, this information is not
        visible to all users, only to superusers and the user owning
        the session being reported on; so it should not represent a
        security risk. This data can be accessed via the
        <structname>pg_stat_activity</structname> system view; refer
        to <xref linkend="monitoring"> for more information.

Seems we should document this somewhere even if the behavior is correct,
which I don't think it is.

The !(x || y) construct is really ugly and I will fix that in a simple
commit now.
