(v14) pg_stat_database new fields

[Krysztophe]

Beyond pretty graphs, I'm wondering if some of these new fields could be really useful.

Perhaps sessions, sessions_fatal and sessions_killed ?

 * session_time
 * active_time                                          
 * idle_in_transaction_time
 * sessions                                             
 * sessions_abandoned
 * sessions_fatal                                                          
 * sessions_killed

PR #308 added various stats from these fields.

There's no thresholds supported on them yet, because we couldn't find any important one (see #305 and #308). This is mostly a service providing some useful performance metrics.

If anyone want to argue here, please do before we close this issue.
