Interestingly, on my machine, rmtree coped with a mode 0 directory just fine, but mode 0400 was more than its tiny brain could handle, so the originally committed fix had code to revert 0400 back to 0700, but I didn't add similar code to revert from 0 back to 0700 because that was working fine. -- Robert Haas EnterpriseDB: http://www.enterprisedb.com The Enterprise PostgreSQL Company
