# 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:
#
# 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-
#
# For more information on Darwin/Mac OS X startup bundles, see this article:

# 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 utitlity

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