I suggest that pageinspect functions are more convenient to use via the
get_raw_page interface, that is, instead of reading the buffer
themselves, the buffer is handed over from elsewhere and they receive it
as bytea. This enables other use cases such as grabbing a page from one
server and examining it in another one.
