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.

# 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:
|
|
#
|
|
# POSTGRESQL=-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:
|
|
#
|
|
# POSTGRESQL=-NO-
|
|
#
