# postgres.init Start postgres back end system. # postgres.init Start postgres back end system.
# #
# Author: Thomas Lockhart <Thomas.Lockhart@jpl.nasa.gov> # Author: Thomas Lockhart <lockhart@alumni.caltech.edu>
# based on news startup by David Myers # modified from other startup files in the RedHat Linux distribution
# #
# Written for RedHat Linux but should apply to other Linux distributions. # 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:
# To be installed as /etc/rc.d/init.d/postgres.init # local5.* /var/log/postgres
# Softlink into rc5.d to bring up with multiuser and networking: # and then set USE_SYSLOG to "yes" below
# cd /etc/rc.d/rc5.d; ln -s ../init.d/postgres.init S98postgres
#
# Assumptions:
# - the postgres user is named "postgres"
# - the postgres user is running csh/tcsh
# #
#PGBIN="/opt/postgres/current/bin" # not used
PGACCOUNT="postgres" # the postgres account (you called it something else?)
POSTMASTER="postmaster" # this probably won't change
USE_SYSLOG="yes" # "yes" to enable syslog, "no" to go to /tmp/postgres.log
FACILITY="local5" # can assign local0-local7 as the facility for logging
PGLOGFILE="/tmp/postgres.log" # only used if syslog is disabled
PGOPTS="-B 256"
#PGOPTS="-i -B 256" # -i to enable TCP/IP rather than Unix socket
# Source function library. # Source function library.
