-# PostgreSQL RDBMS Server

-
-# PostgreSQL boot time startup script for 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:
-#
-# POSTGRESQL=-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:
-#
-# POSTGRESQL=-NO-
-#
-# Created by David Wheeler, 2002
-
-# 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 utility
-
-# use the below command in order to correctly start/stop/restart PG with log rotation script:
-# SystemStarter [start|stop|restart] PostgreSQL
