Hi,

When trying to to set shared_buffers greater then 3,5 GB on 32 GB x86
machine with solaris 10 I running in this error:
FATAL: requested shared memory size overflows size_t

The solaris x86 ist 64-bit and the compiled postgres is as well 64-bit.
Postgresql 8.2.5.
max-shm ist allowed to 8GB.

projmod -s -K "project.max-shm-memory=(priv,8G,deny)" user.postgres


Does anybody have an idea?

Thanks.
Uwe
