max semaphores and semaphore sets?

Still trying to port PostgreSQL which is now reporting the following to me:
“… occurs when either the system limit for the maximum number of
semaphore sets (SEMMNI), or the system wide maximum number of
semaphores (SEMMNS), would be exceeded. You need to raise the
respective kernel parameter. Alternatively, reduce PostgreSQL’s
consumption of semaphores by reducing its max_connections parameter
(currently 32).”

What are the equivalents in QNX RTP? Where can one change them?

thank you
