Log message:
	Tweak default memory context allocation policy so that a context is not
	given any malloc block until something is first allocated in it; but
	thereafter, MemoryContextReset won't release that first malloc block.
	This preserves the quick-reset property of the original policy, without
	forcing 8K to be allocated to every context whether any of it is ever
	used or not.  Also, remove some more no-longer-needed explicit freeing
	during ExecEndPlan.
