Aha, google thinks it's wise to make the last postings (probably if more than n ?) show only the poster name and make the name clickable. Not very userfriendly :-( but now i know it ;-) Sorry if that wasn't clear. I'm getting the same log entry as the original poster, i.e.: LOG: could not truncate directory "pg_subtrans": apparent wraparound. I'm just running an analysis of the "daily transaction id consumption" on my databases to see, if the uptime of the server matches with the time the wraparound was logged. Gerhard
