Re:

Maybe try getting postgresql-7.0.tar.gz. from www.postgresql.org.  Then do
something like the following commands:

su -
groupadd postgres
adduser postgres
    Note: make postgres user with default group postgres
cd /usr/local/src
tar -xvzf postgresql-7.0.tar.gz
cd postgresql-7.0
less INSTALL
./configure
    --prefix=/usr/local/pgsql
    --with-perl --with-tcl
    --with-maxbackends=256
make
make install
cd doc
make install
cd /usr/local
chown -R postgres:postgres pgsql
cd /etc
vi profile
    Note:    add /usr/local/pgsql/bin to PATH
        add /usr/local/pgsql/man to MANPATH
        set PGLIB=/usr/local/pgsql/lib
        set PGDATA=/usr/local/pgsql/data
    Then exit and log back in to take effect.
su - postgres
initdb
exit

Now you can start the database.  To start it, you can use pg_ctl that comes
with postgresql, or you can make a script like the following
/etc/rc.d/init.d/postgresql:

#!/bin/sh
# See how we were called.
case "$1" in
  start)
        # Start daemons.
        echo -n "Starting postgres Postmaster daemon:"
        if [ -z "`pidof -s postmaster`" ]
        then
                su postgres -c "/usr/local/pgsql/bin/postmaster -S -D /usr/local/pgsql/data &"
                echo -n " postmaster"
        else
                echo -n " (already running)"
        fi
        echo
        #touch /var/lock/subsys/postgres
        ;;
  stop)
        # Stop daemons.
        echo -n "Shutting down postgres Postmaster daemon: "
        killall -TERM postmaster 2>/dev/null
        killall -TERM postgres 2>/dev/null
        echo postmaster postgres
        rm -f /tmp/.s.PGSQL.5432
        ;;
  *)
        echo "Usage: postgres {start|stop}"
        exit 1
esac
exit 0

Now start the database:
/etc/rc.d/init.d/postgresql start
You will have to add this into your startup scripts.
/etc/rc.d/init.d/postgresql stop,  can be put in your shutdown scripts.

Then do the following with the server started:

su - postgres
createuser <some username>
    Do this for each user you will have.

Once you have your user created, you can login to the user and run:

createdb
    Note: creates a database called <username> by default.
psql
    Note: connect to your <username> database by default.

At this point you'll be able to start using SQL and create tables etc.
I think these instructions are ok.  Hope it helps.
