This patch is to add more comments

to postgres.init.sh , clairify the options
available, and to add easy support
for installation of postgres into the
runlevel system.

"sh postgres.init.sh install"

Will now install "postgres" in the
/etc/rc.d/init.d directory and execute
/sbin/chkconfig to hook up the symbolic
links.  An uninstall option is also added.

Enclosed is the patch and the patched file

-# postgres.init Start postgres back end system.
+# postgres.init.sh - This script is used to start/stop 
+#                    the postgreSQL listener process.

-# Author:       Thomas Lockhart <lockhart@alumni.caltech.edu>
-#               modified from other startup files in the RedHat Linux distribution
+# Usage
 #
-# This version can log backend output through syslog using the local5 facility.
-# To enable this, edit /etc/syslog.conf to include a line similar to:
-#   local5.*  /var/log/postgres
-# and then set USE_SYSLOG to "yes" below
+#   You can use this script manually, and/or you
+#   can install this script into the runlevel system
+#   by running "sh postgres.init.sh install"
