I'm not a big fan of flags, preferring good defaults. But I was not
bold enough to suggest this as a new default, as someone would probably
want the opposite flag. If you're measuring total server load (rather
than analyzing an application), you may want to see pg_dump activity.
As for a "general" solution: one could add the ability to inject
arbitrary sql just prior to a dump run. That would let someone roll
their own by injecting "SET stats_block_level = false", or make any
other arbitrary settings changes.
Or one might slice the statistics collector by role or user (so your
'backup' role would keep a separate tally).
On the other hand, the flag's advantage is simplicity and directness.
