I think I've seen a handful of reports of performance differences
with different BLCKSZ builds (perhaps not all on community lists).
My recollection is that some people sifting through data in data
warehouse environments see a performance benefit up to 32KB, but
that tests of GiST index performance with different sizes showed
better performance with smaller sizes down to around 2KB.
