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.
