Hi Team, We have observed that xact_start time is null for some period and suddenly it populates to very old value. We have a query which runs every minute to report any transactions running for long time. That query reports nothing continuously for a minute before and suddenly it reports one transaction which is running for more than one day. Is there something wrong here in populating xact_start time in pg_stat_activity? Shall we go with any other approach to detect long running transaction in database? Can someone guide on this?
I went through a thread - https://www.postgresql.org/message-id/20140424101827.2714.39486%40wrigleys.postgresql.org but not sure where it concluded. Appreciate your response. We are using AWS RDS 11.4. Regards,-Virendra
