It seems that errors due to this problem would be transient, and you'd have to be doing something strange, like increasing vacuum_defer_cleanup_age on the fly. If you're seeing the same error on the same TOAST table and TOAST value repeatedly, there's something else going on. More details might help us figure out what. -- Robert Haas EnterpriseDB: http://www.enterprisedb.com The Enterprise PostgreSQL Company

Hello friends, Thanks for your useful inputs. We are facing this issue and want to analyse this through logging. can you please share a sample Postgres config file to enable max logging with syslog support? What should be the debug level so that I can capture the failure information?

I don't think that cranking up the debug level is going to help you here. Instead, you should tell us what you did that ended up causing this error, especially if it is a reproducible series of steps, because then we might be able to identify the cause, and/or fix it. It is worth noting that one possible explanation for this is that your database is corrupted. That can happen for a variety of reasons, as I explained in one of my blog posts: http://rhaas.blogspot.com/2012/03/why-is-my-database-corrupted.html You should check and make sure that none of those causes sound like things that could have happened in your case. -- Robert Haas EnterpriseDB: http://www.enterprisedb.com The Enterprise PostgreSQL Company
