Hi Tom, I looked into another system I have and after updating FC4 to the latest and installing the latest from the PGDG srpms, I didn't have this problem.
Tomorrow I'm going to do a similar test on another server that I have to install Postgres on. I will report back with what I find on it. But on this machine the change to su solved the issue. Some more clues that might help you see if there's a real problem, is that the /var/lib/pgsql/data/postmaster.pid file is created with the a SELinux context that's different from the rest. It is created with system_u:object_r:file_t while the rest of the files are created with root:object_r:postgresql_db_t. And the postmaster (when using runuser) fails on accessing it according to the audit log. The file is created but it's empty. So the failure is when trying to write the pid and the rest of the info to it. When I run with su, it is be able to access it just fine. I retested now just to make sure I wasn't seeing things. Some more info about the system: * FC4 fully updated * Postgres 8.1.3 built from the PGDG SRPMs * Dual Opteron * 4GB RAM * /var/lib/pgsql/data on a RAID10 with xfs on top * WAL on a different RAID on a partition only for itself with ext2 * SELinux in targeted policy mode Bye, Guy.
