This meritates a comment. Code readers may get confused.

I was just looking at the tsearch code which uses pg_strcmpcase, and
those are defined with makeDefElem() so you should switch to strcmp in
this case as well, no? If I patch the code myself I would get an error
when double-quoting, making those command more consistent with the
rest of what you are patching here:
create extension unaccent;
alter text search dictionary unaccent (Rules = 'unaccent'); -- ok
alter text search dictionary unaccent (RuLes = 'unaccent'); -- ok
alter text search dictionary unaccent ("Rules" = 'unaccent'); -- error
--
