Thread: pgsql: Add pg_shmem_allocations view.

Add pg_shmem_allocations view.

This tells you about allocations that have been made from the main
shared memory segment. The original patch also tried to show information
about dynamic shared memory allocation as well, but I decided to
leave that problem for another time.

This should have included a catversion bump.  It's moot now because
I just pushed another change that had one, but ...

            regards, tom lane
