Hello,
Hope there are users in this group w/ PostgreSQL familiarity and this
BSD interaction
I am setting up postgreSQL and have ran into a problem related to either

kernel config or operating within 'the jail'.

Some interactions w/ the postgresql user groups ==>

Systems:  PostgreSQL version 7.2.1, with all default settings on a
  BSD platform  ,4.5-RELEASE FreeBSD.


       hostname# initdb -D /usr/local/pgsql/data
        The files belonging to this database system will be owned
     by user "postgres".
        This user must also own the server process.

        Fixing permissions on existing directory
     /usr/local/pgsql/data... ok
        creating directory /usr/local/pgsql/data/base... ok
        creating directory /usr/local/pgsql/data/global... ok
        creating directory /usr/local/pgsql/data/pg_xlog... ok
        creating directory /usr/local/pgsql/data/pg_clog... ok
        creating template1 database in
     /usr/local/pgsql/data/base/1...
        IpcSemaphoreCreate: semget(key=1, num=17, 03600) failed:
     Function not implemented

        initdb failed.


   Any ideas on the semget() function, remembered reading on it
somewhere before but
   can't remember where
   I hope this does not call for a kernel rebuild
   I did an ipcs -s which ===>


            hostname# ipcs -s
            Semaphores:
            T     ID     KEY        MODE       OWNER    GROUP

           hostname#


   Any insight on this type of problem?

Response ===>
  Hmm, usually this means either the kernel's not configured for SYSV
ipc
  or that you're running in a jail and the sysctl to let the jail use
  sysv ipc is not turned on.


Is this a plausible explanation, & if it is that  the kernel's not
configured for SYSV ipc
or that I am running in a jail how can the sysctl be turned on to allow
the jail to use sysv ipc?

 Thanks

I've spoken w/ my ISP, Tech. support personnel not quite familiar w/
problem but promised to investigate.
Any other experienced opinions welcomed ...
