Do we really need it to be that tight? I know we only have 3 methods today, but 8 doesn't seem that far away. If there were six bits reserved for this I'd be happier. >> # We also add a restriction that block sizes for all 3 of the memory >> # allocators cannot be 1GB or larger.

Losing MemoryContextAllocHuge would be very bad, so I assume this comment is not telling the full truth. regards, tom lane
