Problem restarting server

Hi!

I'm new at using postgreSQL, andI have the following error:


[postgres@nodo2 ~]#  /etc/init.d/postgresql restart
Parando el servicio  postgresql:                           [FALLÓ]
rm: no se puede borrar «/var/run/postmaster.5432.pid»: Permiso denegado
-->> Access Denied
Iniciando servicios postgresql:                            [  OK  ]
[postgres@nodo2 ~]#


That file used to be owned by root, by I changed its ownership, and now
its rights are the following:

-rw-r--r--  1 postgres postgres    6 may 23 10:31 postmaster.5432.pid

But the error stays the same.
What can I do to solve this error?

Apart from that, although it seems that the server is running properly,
it's not true, because when I try whatever, I have this error:

[postgres@nodo2 ~]#  psql
psql: FATAL:  los argumentos de línea de comando no son válidos para
proceso servidor -->> command line arguments are not valid for server
process
HINT:  Pruebe "postgres --help" para mayor información.
[postgres@nodo2 ~]#


Does anybody know why this happens, and what can I do to solve it?

Thanks a lot in advance!

Agustin
