Any tips? Best regards -- JotaComm http://jotacomm.wordpress.com Why do you consider this a problem? Autovacuum is just doing the job it's supposed to do. How big mensagem table is? How many autovacuum workers you have? Does this long-running autovacuum prevent other tables from being vacuumed in-time? Is there some other long running transaction involving this table and preventing autovacuum from doing its job?
