strange semaphore increase

Hi folks,

I've just recognized a strange behavior with the semaphores.
I don't really know how to interpret those numbers, so they might
absolutely ok, though.

I'm using 7.1b4 on a Solaris 2.7 Ultra5.

Each time I stop and start again via pg_ctl the numbers for
the semaphores do increase by 64K?

Is this OK?
Are there actually only 7 semaphores and they are just numbered
that way, or is this the number of semaphores ?
Is that behavior depended on a config setting?

Below is the sequence after a reboot. Before I was already at
about 150000.
