If you're looking for number of transactions then you can query the catalogs as:
$ export myq="select sum(xact_commit+xact_rollback) from pg_stat_database"
$ psql -U postgres -c "$myq" && sleep 60 && psql -U postgres -c "$myq"
sum
-----------
178992891
(1 row)
sum
-----------
178996065
(1 row)
$ bc -q
scale=3
(178996065-178992891)/60
52.900
Depending on your workload pattern, it's recommended to increase the sleep time.
