Tom Lane c8196c87a7 Adjust postmaster to recognize that a lockfile containing its parent's PID
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.

# PostgreSQL boot time startup script for Darwin/Mac OS X. To install, change
# the "prefix", "PGDATA", "PGUSER", and "PGLOG" variables below as
# necessary. Next, create a new directory, "/Library/StartupItems/PostgreSQL".
# Then copy this script and the accompanying "StartupParameters.plist" file
# into that directory. The name of this script file *must* be the same as the
# directory it is in. So you'll end up with these two files:
#
# /Library/StartupItems/PostgreSQL/PostgreSQL
# /Library/StartupItems/PostgreSQL/StartupParameters.plist
#
# Next, add this line to the /etc/hostconfig file:
#
# POSTGRESQLSERVER=-YES-
#
# The startup bundle will now be ready to go. To prevent this script from
# starting PostgreSQL at system startup, simply change that line in
# /etc/hostconfig back to:
#
# POSTGRESQLSERVER=-NO-
#
# For more information on Darwin/Mac OS X startup bundles, see this article:

# Created by David Wheeler, 2002.
# modified by Ray Aspeitia 12-03-2003 :
# added log rotation script to db startup
# modified StartupParameters.plist "Provides" parameter to make it easier to
# start and stop with the SystemStarter utitlity
# use the below command in order to correctly start/stop/restart PG with log rotation script:
# SystemStarter [start|stop|restart] PostgreSQL
