Hi,
I have been forced to re-buid postgresql 7.4.1 but am encountering a 
problem when i do the following:

1. /usr/local/pgsql/bin/initdb -D /usr/local/pgsql/data

the error I get is as follows:

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
selecting default max_connections... 10
selecting default shared_buffers... 50
creating configuration files... ok
creating template1 database in /usr/local/pgsql/data/base/1... FATAL:  
could not create shared memory segment: Cannot allocate memory
DETAIL:  Failed system call was shmget(key=1, size=1081344, 03600).
HINT:  This error usually means that PostgreSQL's request for a shared 
memory segment exceeded available memory or swap space. To reduce the 
request size (currently 1081344 bytes), reduce PostgreSQL's 
shared_buffers parameter (currently 50) and/or its max_connections 
parameter (currently 10).
         The PostgreSQL documentation contains more information about 
shared memory configuration.

initdb: failed

Any ideas as to how I can rectify this, taking into consideration that 
I am a complete novice in the wonderful world of unix ;-)


regards


Uzo

you will have to edit the file called 'rc' in the top
level etc folder..


in the terminal type

cd /etc
sudo pico rc
(you will be asked for an administrator password)
scroll down 2 to 3 pages and find the section like
this

# System tuning
sysctl -w kern.maxvnodes=$(echo $(sysctl -n
hw.physmem) '33554432 / 512 * 1024 +p'|dc)
sysctl -w kern.sysv.shmmax=167772160
sysctl -w kern.sysv.shmmin=1
sysctl -w kern.sysv.shmmni=32
sysctl -w kern.sysv.shmseg=8
sysctl -w kern.sysv.shmall=65536

after you change the values to look like this, type a
control-x to save and exit. restart your machine.


these are the values that I used and they work. I
don't know if these are the best settings, only that
they work..

Ted

You're out of shared memory.  Did you shut down the old postmaster
before trying this?  The default shared memory size on OS X is not large
enough to run more than one postmaster at a time (unless you reduce
7.4's default shared_buffers and max_connections quite a bit).

If you didn't shut down the old postmaster cleanly (eg you did kill -9
or some such) then the old shared memory segment may still be hanging
around even though it's not in use.  OS X doesn't seem to have ipcs or
ipcrm, so there's no real easy way to check this, and no way to get rid
of such a segment except to reboot :-(.
