# 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
#
#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
