  • clock_timestamp will just return the current timestamp

(the originally proposed version MAX(EXTRACT(EPOCH FROM (clock_timestamp() - xact_start))) AS age_in_seconds is also correct, but return the seconds, not the timestamp.

Using the current version the graphs look like this (flat line as this will always match the current time):
