The initialization fork was added in 9.1, but has not been taken into
consideration in documents of get_raw_page function in pageinspect and
storage layout. This commit fixes those oversights.
get_raw_page can read not only a table but also an index, etc. So it
should be documented that the function can read any relation. This commit
also fixes the document of pageinspect that way.
Back-patch to 9.1 where those oversights existed.

as a substitute for remembering many of the above rules. But keep in
mind that this function just gives the name of the first segment of the
main fork of the relation — you may need to append a segment number
