I'm using scripts in /Library/StartupItems/PostgreSQL

I haven't used a StartupItem for PostgreSQL since launchd was released. I haven't looked too closely at your configuration, but you might consider using a launchd plist instead. Here's one of mine (from /Library/LaunchDaemons/org.postgresql.postgres.v824.plist). Note that if you use one of the plist launchd configuration editors out there you'll probably lose the comments when you save.

Hope this helps.

This launchd.plist file is used by the launchd process (availabie on
Mac OS X 10.4 and later) to launch and shutdown a PostgreSQL server.
The launchd.plist is used instead of a StartupItem. For detailed descriptions of launchd parameters and launchd, refer to to the launchd.plist, launchd, and
launchctl manpages.

launchd.plists are commonly named in a manner similar to preference plist files, so for consistency (and easy identification) launchd.plists for PostgreSQL
server instances should begin with org.postgresql.postgres. When running
multiple server instances on one machine, you may wish to distinguish them. For example, if one of your PostgreSQL servers is 8.0 and another 8.1, you might
name the two launchd.plist files

org.postgresql.postgres.v80.plist
org.postgresql.postgres.v81.plist

Another alternative is to identify them by use. For example, when running one
development server instance and a production server instance on the same
machine, you might name the two launchd.plist files

org.postgresql.postgres.dev.plist
org.postgresql.postgres.prod.plist

Note: While commments in launchd.plist files do not appear to interfere with launchd operation, editing and saving this file using Property List Manager
will *not* preserve comments (including these)!

The first element is the absolute path to the postmaster server application binary, followed by the argments to be passed to the
         postmaster server application. Add, delete, and update these
parameter strings as needed for your requirements. The example includes
         setting the database data directory (PGDATA) and sets the
         redirect_stderr runtime parameter.
