Bug 1057011

Description of problem:

The basic installation fails with the following error message:

[ ERROR ] Failed to execute stage 'Misc configuration': Command '/bin/systemctl' failed to execute

The system log contains the following:

Jan 23 11:00:22 localhost pg_ctl[2141]: FATAL:  could not create shared memory segment: Invalid argument
Jan 23 11:00:22 localhost pg_ctl[2141]: DETAIL:  Failed system call was shmget(key=5432001, size=43753472, 03600).
Jan 23 11:00:22 localhost pg_ctl[2141]: 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 43753472 bytes), reduce PostgreSQL's shared memory usage, perhaps by reducing shared_buffers or max_connections.
Jan 23 11:00:22 localhost pg_ctl[2141]: 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.
Jan 23 11:00:22 localhost pg_ctl[2141]: The PostgreSQL documentation contains more information about shared memory configuration.
