Hello, Thanks a lot for your answers.
> You should get it... > stats_temp_directory | pg_stat_tmp | Writes temporary statistics files to the specified directory. I don't know why i don't get it. I am in 9.1 version... Moreover, when I mount pg_stat_tmp in a tmpfs, the warning messages decrease the warning messages decrease from 1 each minutes to 1 each five secondes. I don't have any others logs warning but the file pg_stat.stat in the mounting point is not created... I tryed before on a test environment and it works... If you have any ideas... Thanks a lot.
