COPY can t make file

Hello out there,

I've found a somehow strange behaviour of postgreSQL 7.0; consider the
following:

  1. user umehlig, in psql:
  =========================
  db=# COPY blatt TO '/usr/local/tmp/blatt.txt' USING DELIMITERS '|' with null as '';
  ERROR: COPY command, running in backend with effective uid 1100,
  could not open file '/usr/local/tmp/blatt.txt' for writing.  Errno =
  Keine Berechtigung (13). -- "Keine Berechtigung": "no permission"

  2. user postgres, outside psql:
  ===============================
  [postgres@pandora3 pgsql]$ grep 1100 /etc/passwd
  postgres:*:1100:1100:PostgreSQL Super User:/usr/local/pgsql:/bin/sh
  [postgres@pandora3 pgsql]$ grep postgres /etc/group
  users::100:umehlig,postgres
  postgres:*:1100:postgres
  [postgres@pandora3 pgsql]$ touch /usr/local/tmp/blatt.txt
  [postgres@pandora3 pgsql]$ ls -ld /usr/local/tmp/ /usr/local/tmp/blatt.txt
  drwxrwxr-t   3 root     users         144 May 29 21:47 /usr/local/tmp/
  -rw-rw-r--   1 postgres postgres    19011 May 29 21:48 /usr/local/tmp/blatt.txt

  3. user umehlig, in psql:
  =========================
  db=# COPY blatt TO '/usr/local/tmp/blatt.txt' USING DELIMITERS '|' with null as '';
  COPY

The COPY command does succeed only after manually generating the file
-- is there something wrong with my permissions, or is there something
wrong with the COPY command?

Thanxs,
Ulf
