Postgresql and Sparc?

[snorkel]

emerged it and when I start it I get this in the log:
IpcMemoryCreate: shmget(key=5432001, size=34275328, 03600) failed: Invalid argument

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 34275328 bytes), reduce
PostgreSQL's shared_buffers parameter (currently 2048) and/or
its max_connections parameter (currently 1024).

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 Administrator's Guide contains more information about
shared memory configuration.

I can't find SHMMAX param in the kernel, any idea's
