# description: PostgreSQL RDBMS
|
|
|
|
# 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). To do that, uncomment these
|
|
# three lines:
|
|
#PG_OOM_ADJUST_FILE=/proc/self/oom_score_adj
|
|
#PG_MASTER_OOM_SCORE_ADJ=-1000
|
|
#PG_CHILD_OOM_SCORE_ADJ=0
|
|
# Older Linux kernels may not have /proc/self/oom_score_adj, but instead
|
|
# /proc/self/oom_adj, which works similarly except for having a different
|
|
# range of scores. For such a system, uncomment these three lines instead:
|
|
#PG_OOM_ADJUST_FILE=/proc/self/oom_adj
|
|
#PG_MASTER_OOM_SCORE_ADJ=-17
|
|
#PG_CHILD_OOM_SCORE_ADJ=0
