These are the index methods and the valid lists for each.  The docs are
correct in how they remove duplication.  I'm undecided on whether that is
the best presentation choice.  I would at minimum place a new paragraph
after "own set of allowed storage parameters." so that "The B-tree,
hash..." begins its own line.

B-tree:
fillfactor
deduplicate_items

Hash:
fillfactor

Gist:
fillfactor
buffering

SP-Gist:
fillfactor

GIN:
fastupdate
gin_pending_list_limit

BRIN:
pages_per_range
autosummarize
