Auto Starting +/or Shutdown on OS X

I'm using scripts in /Library/StartupItems/PostgreSQL

PostgreSQL starts manually just fine via
/usr/local/pgsql/bin/pg_ctl -D /usr/local/pgsql/data -l
/usr/local/pgsql/logfile start

PostgreSQL will not start on System restart using files in
/Library/StartupItems/PostgreSQL (See below).

If I execute the start command above just after a System start I get
    pg_ctl: another server may be running; trying to start server anyway
    server starting
and then it starts and runs fine.

If I shut down PG using
   pg_ctl stop (no users connected)
it stops and subsequently starts using code above just fine, w/o the
warning.

---
I added the command:
   date > /Users/showmefile
to appropriate portions of /Library/StartupItems/PostgreSQL/PostgreSQL
as seen below, and the script portions ARE appropriately being executed.

How come shutdown isn't clearing things up?
Or is the problem in the startup?

Thanks!

# PostgreSQL boot time startup script for Darwin/Mac OS X. To install,
change
# the "prefix", "PGDATA", "PGUSER", and "PGLOG" variables below as
# necessary. Next, create a new directory,
"/Library/StartupItems/PostgreSQL".
# Then copy this script and the accompanying "StartupParameters.plist" file
# into that directory. The name of this script file *must* be the same
as the
# directory it is in. So you'll end up with these two files:
#
#    /Library/StartupItems/PostgreSQL/PostgreSQL
#    /Library/StartupItems/PostgreSQL/StartupParameters.plist
#
# Next, add this line to the /etc/hostconfig file:
#
# POSTGRESQLSERVER=-YES-
#
# The startup bundle will now be ready to go. To prevent this script from
# starting PostgreSQL at system startup, simply change that line in
# /etc/hostconfig back to:
#
# POSTGRESQLSERVER=-NO-
#
# For more information on Darwin/Mac OS X startup bundles, see this article:

# modified by Ray Aspeitia 12-03-2003 :
# added log rotation script to db startup
# modified StartupParameters.plist "Provides" parameter to make it
easier to
# start and stop with the SystemStarter utitlity

# use the below command in order to correctly start/stop/restart PG with
log rotation script:
# SystemStarter [start|stop|restart] PostgreSQL
