feature idea - "stats mode"

[kmoppel]

Show only counts of active connections, exceptions, tx, load, xlog written (and other available numeric values) as 10s,1m,5m averages. Even better would be graphs. Currently there is no memory besides "uptime" available, so it's impossible to see if there has been some recent change in metrics if we keep pg_view running in background while we do some ops.

@alexeyklyukin Hey, can we close this issue? It dates back to March 2016.

Or, we could add a "Help Wanted" label, and maybe @kmoppel or someone else would like to work on it.
