Thanks for the info. It's a little bit overkill for my purpose though. (on busy systems, the notification would be too frequent). I would think that creating a small routine periodically consults pg_stat_all_tables view and records the last update datetime for each table (unfortunately the view does not have last modification date). -- Tatsuo Ishii SRA OSS, Inc.
