I've simplified the Darwin/Mac OS X startup script I submitted earlier

in the year. This version has only the two files required by the Darwin
startup bundle design. Plus the sh script now uses Darwin-standard
functions to start up PostgreSQL, and it checks for the presence of a
variable in /etc/hostconfig, as do other Darwin startup scripts.

I suggest that a new directory be created,
contrib/start-scripts/darwin, and that these two files be put into it.
Folks who want to use the script can read the comments inside it to
figure out how to use it.

+# 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/PostgreSQLStartupParameters.plist
+#
+# Next, add this line to the /etc/hostconfig file:
+#
+# POSTGRESQLSERVER=-YES-
+#
+# The startup bundle will now be read to go. To prevent this script from
+# starting PostgreSQL at system startup, simply change that line in
+# /etc/hostconfig to:
+#
+# POSTGRESQLSERVER=-NO-
