Re: error while starting database - Mailing list pgsql-bugs

If it is true that listing /tmp (ls -a /tmp) returns no such file or
directory, then that may be the problem.  You should have a world-
writable /tmp folder, as Tom already pointed out.  Also, an update to
a more stable version of PostgreSQL is still highly recommended.
