Greetings, For a big application, I want to generate reports from the database and keep these on-line as long as they reflect the actual contents of the database. I only want to regenerate the reports when needed, i.e., when the database contents have changed. I'm sure PostgreSQL can tell me when the last update has been COMMITted but until now I haven't been able to find out how. I must have used the wrong search terms... Can anyone tell me how to find the last update time of a database? Thanks, Johan
