"postgres" has long been officially preferred over "postmaster" as the name of the program to invoke to run the server. Some example scripts and code comments still used the latter. Change those.

# 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
