# This is an example of a start/stop script for SysV-style init, such
# as is used on Linux systems.  You should edit some of the variables
# and maybe the 'echo' commands.
#
# Place this file at /etc/init.d/postgresql (or
# /etc/rc.d/init.d/postgresql) and make symlinks to
#   /etc/rc.d/rc0.d/K02postgresql
#   /etc/rc.d/rc1.d/K02postgresql
#   /etc/rc.d/rc2.d/K02postgresql
#   /etc/rc.d/rc3.d/S98postgresql
#   /etc/rc.d/rc4.d/S98postgresql
#   /etc/rc.d/rc5.d/S98postgresql
# Or, if you have chkconfig, simply:
# chkconfig --add postgresql
#
# Proper init scripts on Linux systems normally require setting lock
# and pid files under /var/run as well as reacting to network
# settings, so you should treat this with care.

# It's often a good idea to protect the postmaster from being killed by the
# OOM killer (which will tend to preferentially kill the postmaster because
# of the way it accounts for shared memory).  Setting the OOM_SCORE_ADJ value
# to -1000 will disable OOM kill altogether.  If you enable this, you probably
# want to compile PostgreSQL with "-DLINUX_OOM_SCORE_ADJ=0", so that
# individual backends can still be killed by the OOM killer.
#OOM_SCORE_ADJ=-1000
# Older Linux kernels may not have /proc/self/oom_score_adj, but instead
# /proc/self/oom_adj, which works similarly except the disable value is -17.
# For such a system, enable this and compile with "-DLINUX_OOM_ADJ=0".
#OOM_ADJ=-17
