PG 8.0.3 ignores parameter listen_addresses ?

Hi,

I compiled a Postgres 8.0.3 on a SuSE 9.3 system.
This sytem has several network-interfaces. One points to the wild internet.

Now I'd like postgres only to listen for localhost, the LAN and probaply
the socket.
I wrote listen_addresses = 'localhost,192.168.100.1' in the
postgresql.conf restartet the pg-server and looked with netstat -lan
|grep 5432.

It still showed
tcp        0      0 0.0.0.0:5432            0.0.0.0:*               LISTEN
tcp        0      0 :::5432                 :::*                    LISTEN
unix  2      [ ACC ]     STREAM     LISTEN         65292  /tmp/.s.PGSQL.5432

Uncommenting the listen_addresses = 'localhost' in the default conf-file
does the same.
Nothing, that is. :(

I though that perhaps PG reads some other file but as I changed the port
to 5433 in the next parameter below the listen_addresses it worked.


Where am I wrong ?
