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 Clark

# postgres.init.sh - This script is used to start/stop

# the postgreSQL listener process.

|

# 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"
