FWIW, I see that port/win32/error.c translates these Windows error codes to EACCES: ERROR_ACCESS_DENIED ERROR_CURRENT_DIRECTORY ERROR_LOCK_VIOLATION ERROR_SHARING_VIOLATION ERROR_NETWORK_ACCESS_DENIED ERROR_CANNOT_MAKE ERROR_FAIL_I24 ERROR_DRIVE_LOCKED ERROR_SEEK_ON_DEVICE ERROR_NOT_LOCKED ERROR_LOCK_FAILED It would appear that the underlying problem is one of these. regards, tom lane
