[Bug 653507] [NEW] [Lucid] Postgresql cannot start because of SHMMAX configuration

[Dmitry "Divius" Tantsur]

Public bug reported:

$ sudo service postgresql-8.4 start
 * Starting PostgreSQL 8.4 database server                                                                                                                    * The PostgreSQL server failed to start. Please check the log output:
2010-10-02 14:24:41 MSD FATAL:  could not create shared memory segment: ???????????? ????????
2010-10-02 14:24:41 MSD DETAIL:  Failed system call was shmget(key=5432001, size=36880384, 03600).
2010-10-02 14:24:41 MSD HINT:  This error usually means that PostgreSQL's request for a shared memory segment exceeded your kernel's SHMMAX parameter.  You can either reduce the request size or reconfigure the kernel with larger SHMMAX.  To reduce the request size (currently 36880384 bytes), reduce PostgreSQL's shared_buffers parameter (currently 4096) and/or its max_connections parameter (currently 103).
	If the request size is already small, it's possible that it is less than your kernel's SHMMIN parameter, in which case raising the request size or reconfiguring SHMMIN is called for.
	The PostgreSQL documentation contains more information about shared memory configuration.

Used to work with previous kernel.
