starting PgSQL w/ launchd on OSX 10.4.2 - Mailing list pgsql-ports

hi all,

after much help/education elsewhere re: building a launchd .plist for apache2,
etc., i'm on to postgresql ...

my 'original' and fully functional StartupItem string(s) for pgsql is(are):

    cd /var/Settings/PgSQL/
    sudo -u pgsuser
    sh -c "nohup /usr/local/pgsql/bin/postmaster -d 5 -n -i -h 10.0.0.6 -D
/var/Data/PgSQL -c config_file=/var/Settings/PgSQL/postgresql.conf </dev/null
>>/var/Logs/postgresql_stderror.log &"

never a problem with it ... and any/all attempts to use/launch are correctly
AND informatively/verbosely logged in BOTH my system.log & postgresql_stderror.

now, on to a launchd .plist ...

i've googled for scripts online (e.g., here: N Tulach,
<http://archives.postgresql.org/pgsql-ports/2005-05/msg00005.php>), and with a
few mods am using:

==========================================================

on 'launchctl load', my syslog shows only (again!):

    Jul 26 09:21:54 devuser launchd: org.postgresql.postmaster: exited with
    exit code: 1
    Jul 26 09:21:54 devuser launchd: org.postgresql.postmaster: respawning too
    quickly! throttling
    Jul 26 09:21:54 devuser launchd: org.postgresql.postmaster: 9 more failures
    without living at least 60 seconds will cause job removal
    Jul 26 09:21:54 devuser launchd: org.postgresql.postmaster: will restart in
    10 seconds

with apache, these errors were elim'd by a combo of:

    adding "-D FOREGROUND"
    removing UserName & GroupName

with PostgreSQL, however (from
<http://www.postgresql.org/docs/current/static/postmaster-start.html>):

  "Thus, the simplest way to start the server is:
     $ postmaster -D /usr/local/pgsql/data
   which will leave the server running in the foreground. This must be done
while logged into the PostgreSQL user account"


which would seem to indicate that:

  (a) postmaster DEFAULTS to the foreground, and hence, does NOT need a flag to
do so
  (b) postmaster must be run as the postgresql user/group


QUESTIONS:

  any ideas why launchd is 'acting up' w.r.t PostgreSQL? and, what to do abt it?

cheers,
