Log message:
	Although we can't support out-of-line TOAST storage in indexes (yet),
	compressed storage works perfectly well.  Might as well have a coherent
	strategy for applying it, rather than the haphazard store-what-you-get
	approach that was in the code before.  The strategy I've set up here is
	to attempt compression of any compressible index value exceeding
	BLCKSZ/16, or about 500 bytes by default.
