It could be a CLUSTER or an REINDEX or something like that, but my best guess is that it is an autovacuum on that table that is doing it. Based on the low time between the messages, I'd also speculate that there is an autovacuum in the same database being done for anti-wrap around purposes, and you are falling afoul of this: http://www.postgresql.org/message-id/CAMkU=1yzczv-yu-ysjxypnbssri76_ijcpm_+adaat_+24h...@mail.gmail.com It is probably nothing to worry about. The presence of LOG messages which have not been specifically requested doesn't mean you have a problem, it just means that if you *do* have an empirical problem, this would be a good place to start investigating it.
