script. To do this, have pg_ctl pass down its parent shell's PID in an environment variable PG_GRANDPARENT_PID, and teach CreateLockFile() to disregard that PID as a false match if it finds it in postmaster.pid. This allows us to cope with one level of postgres-owned shell process even with pg_ctl in the way, so it's just as safe as starting the postmaster directly. You still have to be careful about how you write the initscript though. Adjust the comments in contrib/start-scripts/ to not deprecate use of pg_ctl. Also, fix the ROTATELOGS option in the OSX script, which was indulging in exactly the sort of unsafe coding that renders this fix pointless :-(. A pipe inside the "sudo" will probably result in more than one postgres-owned process hanging around.

# 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.
