add client_addr to metric pg_stat_activity_max_tx_duration
@SuperQ I don't think most users have so much more client hosts than postgres-users to make the client_addr-label problematic. But sure, this introduces another factor to the amount of monitoring data.
Would it be ok for you to make this change opt-in using a CLI flag?
An opt-in flag would be fine. The only issue is that this collector setup hasn't been moved to our new collector package, so it's possibly slightly difficult to implement here.
I don't know that we have had a good example of customizing a collector that has been ported to the collector package either. I remember another request noting that the constructors for collectors don't have an obvious pattern for customization. @SuperQ Do we have a good example from another exporter for customizing collectors?
