Обсуждение: 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

Look again --- you seem to have invoked "postgres", not "psql".  There
is seldom any reason to invoke the "postgres" program directly.

If you really did type "psql" then your installation is messed up
(somehow postgres got copied over psql, I suppose).  Might be easiest
to remove and reinstall the programs.

What's the difference between "postgres" and "psql"?

postgres is the server and psql is a client used to pass queries to the
server from a command line or in a batch script.
