starting postgres/psql

Back again,I still cant access the dbms I have created the user postgres
and started postgres.

[root@localhost bob]# su postgres
bash-2.05b$ /usr/local/pgsql/bin/pg_ctl -D /usr/local/pgsql/data -l
logfile start
/usr/local/pgsql/bin/pg_ctl: line 341: logfile: Permission denied
postmaster successfully started

this brings me to the bash-2. 05b$ prompt where I tried

bash-2.05b$ psql -d template1
bash: psql: command not found
bash-2.05b$

so how do I get access?
