must be stale. Tweak example startup scripts to not use pg_ctl but launch the postmaster directly, thereby ensuring that only the postmaster's direct parent shell will be a postgres-owned process. In combination these should fix the longstanding problem of the postmaster sometimes refusing to start during reboot because it thinks the old lockfile is not stale.

# 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.
