I am using pgsql9.0b4 (but pgsql8.4 exhibits the same behavior) on MacOS 10.6.4
and initdb fails:
/usr/local/pgsql90beta/bin/initdb -D /Volumes/Data/pgsql90b/ -E UTF8
The files belonging to this database system will be owned by user "agentm".
This user must also own the server process.
The database cluster will be initialized with locale en_US.UTF-8.
The default text search configuration will be set to "english".

creating template1 database in /Volumes/Data/pgsql90b/base/1 ... FATAL: could
not create shared memory segment: Cannot allocate memory
DETAIL: Failed system call was shmget(key=1, size=1703936, 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 1703936 bytes), reduce PostgreSQL's shared_buffers parameter
(currently 50) and/or its max_connections parameter (currently 14).
The PostgreSQL documentation contains more information about shared
memory configuration.
child process exited with exit code 1
initdb: removing data directory "/Volumes/Data/pgsql90b"
I would like to create the database space and then reduce the shared memory
requirements in postgresql.conf, but this situation seems to create a
chicken-and-egg problem. How can I reduce shared_buffers or max_connections
prior to running initdb?
Cheers,
M
