Have you tried using PgAdmin?  It may help you a bit...  Then just iron
out the details afterwards...;-)  It's somewhere in
www.greatbridge.com... I think..;-)

try a

netstat -a | grep postgres

This is how it is started in my machine...;-(

su -l postgres -c "/usr/bin/pg_ctl  -D $PGDATA -p /usr/bin/postmaster
start >/dev/null 2>&1"


The -i option is with /var/lib/pgsql/data/postmaster.opts in my
machine...

As for PGDATA, it's in the script...

    if [ -f /var/lib/pgsql/PG_VERSION ] && [ -d
/var/lib/pgsql/base/template1 ]
    then
        export PGDATA=/var/lib/pgsql
    else
        export PGDATA=/var/lib/pgsql/data
    fi

What version of PostgreSQL are you running?  What O.S. are you running
it in?  And how did you install postgresql?
