Log Message: ----------- Tweak dynahash.c to avoid wasting memory space in non-shared hash tables. palloc() will normally round allocation requests up to the next power of 2, so make dynahash choose allocation sizes that are as close to a power of 2 as possible. Back-patch to 8.1 --- the problem exists further back, but a much larger patch would be needed and it doesn't seem worth taking any risks.
