Hello, since I have enabled "stats_temp_directory = '/run/shm'" in /etc/postgresql/9.1/main/postgresql.conf I get the following error: 2014-04-21 02:37:29 CEST LOG: could not rename temporary statistics file "/run/shm/pgstat.tmp" to "/run/shm/pgstat.stat": No such file or directory /var/run/shm# ls -rtl -rw------- 1 postgres postgres 312211 Apr 22 11:31 pgstat.stat There is no "/run/shm/pgstat.tmp" file but if I create it and change the owner to postgres the file will be removed few minutes later. How can explain and how can I solve this "error"? Regards, Basti

When Postgres has no permission why "pgstat.stat" is created by postgres? I have also try to create a file via su postgres -c "cd /run/shm/ && touch ...." /run# ls -la shm total 52 drwxrwxrwt 2 root root 100 Apr 22 16:09 . drwxr-xr-x 20 root root 660 Apr 8 11:15 .. -rw-r--r-- 1 postgres postgres 0 Apr 22 16:09 file_create_as_postgres_user -rw------- 1 postgres postgres 52658 Apr 22 16:09 pgstat.stat -rw-r--r-- 1 root root 0 Oct 19 2012 .tmpfs /run# ls -rtl | grep shm drwxrwxrwt 2 root root 80 Apr 22 16:02 shm I think these permissions are enough.

Some thoughts. Is there more than one instance of Postgres on this machine and could there be a conflict?

If you happen to have multiple postgres instances, chances are that one is running as some user other than postgres. That would explain why it can't modify those files. -- If you can't see the forest for the trees, Cut the trees and you'll see there is no forest.
