I think this should be done using event triggers. Right now, you just have it hardcoded to TRUNCATE and DROP TABLE, which seems somewhat arbitrary. With event triggers, you have the full flexibility to do what you want. You can pick which commands to apply it to, you can log the LSN, you can create restore points, etc. -- Peter Eisentraut http://www.2ndQuadrant.com/ PostgreSQL Development, 24x7 Support, Remote DBA, Training & Services
