help-me please!

Hello to all PGSQL Team!!!

Im trying to run PGSQL 7 in my FreeBSD 5.0.

When I run :
# su dataman
# ./postgres -D /usr/home/dataman/var data_torre
i recive the prompt comand like that:

backend>

So, i try at this command prompt : select version();
I recive from postgres:
Postgree 7.31 on 1386.portbld........
I try other command like that: select 2+2;
I recive: 4

Finnaly, i think that is every thing all right on my PostgreSQL Server.
But Im wrong!!!
becouse when i try to connect at the same database "data_torre" with "psql" like that:
# su dataman (user of postgresql)
# psql data_torre
Cold not connect to server: No such file or directory.
Is the server running locally and accepting connections on Unix domain socket "/tmp/.s.PGSQL.5432" ???

I dont know whats happen, the server is running, but the client dont work.
I try other PGSQL Client, like EMS, and I recive the same error message.
Is the server running locally and accepting connections on Unix domain socket "/tmp/.s.PGSQL.5432" ???

Please, can you help-me?
thank you for all, the PGSQL is a very USEFUL program, i hope that i can contribuite.
Bye bye - Bruno Carlini Regginato
