lo_import permissions problem

From
"essay182@gmail.com"

I have been trying to import a file into a table using lo_import and keep getting the error

ERROR: could not open server file "/tmp/myfile": Permission denied

The file is in /tmp so it is world readable and I made sure the file had the correct permissions by doing chmod 777. My user has super user privileges as well. I tried importing other files such as /etc/hosts as a test and this worked fine. I am running Gentoo linux with Postgres 8.0. Does anyone have any idea what the problem is and what I need to do to correct it?

Thanks in advance

Hm, are you sure that the /tmp directory has world execute permissions?

The other thought that comes to mind is that SELinux creates an entire
new level of reasons for permissions failures.  I have no idea whether
or not Gentoo has SELinux or runs it in enforcing mode by default ...

Tom,

Yep I have double checked my permissions on /tmp. You may be right with your suggestion about SELinux. I was actually testing this on two boxes and one is a Fedora box which I believe runs SELinux. I have gotten things to work on the Gentoo box now. It would not work when I was logged in as root, but with a less privileged account on the Gentoo box, things worked.
