Re: could not rename temporary statistics file "/run/shm/pgstat.tmp" to "/run/shm/pgstat.stat": No such file or directory

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.
