StrategyControl is inherent to freelist.c and has no external
declaration so you could not have it even if you the
BGWORKER_SHMEM_ACCESS flag. In order to calculate that, an idea could
be to go through the array of BufferDescriptors and then get the
information necessary. Locks are necessary when doing that if you want
to get a consistent picture of the buffers. Perhaps more experienced
people have better ideas though...
