But pg_stat_statement is a user tool which is expected to have lots of
use, and backwards compatibility concerns because of people who might
have written tools on top of it.  Not so with pageinspect.  I don't
think we need to put in the same amount of effort.  (Even though,
really, it's probably not all that difficult to support both cases.  I
just don't see the point.)
