I am now Linux and PostgreSQL user, have a question

I am new user of linux. and I am interested in Postgresql

recently I download ver7.1 and setup
I do it step by step according some docunment in www.Linuxfab.cx

the docunment I read is in below link

http://linuxfab.cx/indexBookData.php?BID=5&G1=5&G2=2&G3=0&G4=0&PAGEID=1

The problem I got is as below:

P.S. the super user "postgres" is added by myself

[root(at)vtl /root]# su - postgres
[postgres(at)vtl postgres]$ /usr/local/pgsql/bin/initdb -D /usr/loca/pgsql/data
This database system will be initialized with username "postgres".
This user will own all the data files and must also own the server process.

Creating directory /usr/loca/pgsql/data
mkdir: cannot create directory `/usr/loca/pgsql/data': No such file or
directory
initdb failed.
Removing temp file /tmp/initdb.11893.
[postgres(at)vtl postgres]$ /usr/local/pgsql/bin/initdb -D
/usr/local/pgsql/data
This database system will be initialized with username "postgres".
This user will own all the data files and must also own the server process.

Success. You can now start the database server using:

/usr/local/pgsql/bin/postmaster -D /usr/local/pgsql/data
[postgres(at)vtl postgres]$ /usr/local/pgsql/bin/postmaster -D
/usr/local/pgsql/data
\DEBUG: database system was shut down at 2001-04-25 10:48:00 HKT

DEBUG: Redo record at (0, 1522124); Undo record at (0, 0); Shutdown TRUE
DEBUG: NextTransactionId: 615; NextOid: 18720
DEBUG: database system is in production state

the process stoped here, not more action. Can anybody tell me what's wrong?
