Technique - installation | erreur initdb shared_buffers

Par sekaijin le 31/12/2006 - 18:47

Bonjour j'essais d'installer PostgreSQL 8.1.4 sur MacOSX mais je ne parviens pas à initialiser la base.

le message indique de réduire la memoire partagé mais je ne vois pas comment je peux le faire avant qu'il ne me crée le fichier config.

comment configurer initdb ?

voici mes traces

% bin/initdb -D /opt/var/pgsql/data/
The files belonging to this database system will be owned by user "postgre".
This user must also own the server process.

The database cluster will be initialized with locale C.

DETAIL: Failed system call was shmget(key=1, size=1318912, 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 1318912 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.
