Yeah ...

I find it curious that you don't even bother to list "add WAL support to
hash indexes" as a possible solution.  It's certainly doable, and
probably not even very much more work than something like moving hash
support to a contrib module would be.  (Assuming that's even possible,
which I doubt, because the core code relies on hash index opclasses even
if not on hash indexes.)
