How does icmp_seq fit into this? Or was that an oversight?

Also, in standard ping if you don't pass -c it will continue to loop
until interrupted. Would you suggest that pg_ping mimic that, or that
we add an additional flag for that behavior?

FWIW, I would use 'watch' with the existing output for cases that I
would need something like that.
