Re: [HACKERS] WARNING : pgstat wait timeout - Postgres 9.1
About the stats_temp_directory, I didn't run as root... Now I'm sure the configurations are correct. I think, I have too much IO to use stats. I will ever have this message... Maybe I can disable this option. Do you know what it really impact ? Thanks.

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.

[HACKERS] WARNING : pgstat wait timeout - Postgres 9.1
Hello, I am facing a problem with pgstat as my subject says. I known, some topics are open about that, but I would like to go deeper. Some person told that the better way to don't have this message anymore is to configure pgstat.stat to be loaded in the RAM with a tmpfs mount point. What are the consequences ? Because this file will be remove if the server reboot. If we change the parameter stats_temp_directory is it necessary to reboot the server ? When I lauch a SHOW ALL; command, the parameter stats_temp_director is not here. For information, my pgstat.stat file is up to 1,3MB. Thank you for your help. Math
