Field Separator not working?

I'm having troubles setting the field separator. I tried this on pg7.4,
8.0 and 8.1beta, and I always get the same results.

So, from within psql i do:
pulitzer2=# select * from pg_user; usename  | usesysid | usecreatedb | usesuper | usecatupd |  passwd  |
valuntil | useconfig
-----------+----------+-------------+----------+-----------+----------+----------+-----------mario     |        1 | t
       | t        | t         | ******** |
 
|postgres  |      100 | t           | t        | t         | ******** |
|pulitzer2 |      102 | f           | f        | f         | ******** |
infinity |101       |      101 | f           | f        | f         | ******** |
infinity |
(4 rows)

pulitzer2=# \t
Showing only tuples.
pulitzer2=# \f#
Field separator is "#".
pulitzer2=# select * from pg_user;mario     |        1 | t           | t        | t         | ******** |
|postgres  |      100 | t           | t        | t         | ******** |
|pulitzer2 |      102 | f           | f        | f         | ******** |
infinity |101       |      101 | f           | f        | f         | ******** |
infinity |

pulitzer2=#


psql does tell me that I changed the field separator to "#", but it
still uses "|" as separator. I'm parsing the script from bash, using
psql, and setting the field separator options on the command line, but I
get similair results, the field separator is always "|", so I need to
awk-it with -F, but sometimes I have problems because data in my tables
often contain "|" charachter.

I've been looking trough the psql source code, but just like that, it's
too big hassle for me now :)

Am I doing something wrong?
