Does PG set up buffers at the postmaster level or the database level?
If at the database level, then you'll be allocating memory to
databases that might not be in use at any one time, thus wasting it.
One database buffer pool would make more efficient use of RAM.
Shared memory is allocated at the cluster level.
See

ml#RUNTIME-CONFIG-RESOURCE-MEMORY
I read that page, but don't see any references to "cluster level".
Maybe I am misinterpreting "cluster"?
