Since we're hard up against the 9.5beta1 deadline, I've made an executive
decision to commit just the minimal change, which I view as being to
constrain the array size to MaxAllocSize where it has been all along.
I found a second rather serious bug in the new hash code while doing that
--- it failed to ensure nbuckets was actually a power of 2 --- which did
not improve my opinion of it one bit.
It's clear from this discussion that there's room for further improvement
in the hashtable sizing behavior, but I think that's 9.6 material at
this point.
regards, tom lane
