A hash index is probably even less useful than the btree index for
this type, unless it can be used with multi-column indices. Because
the hash will chain duplicate values into a list of some kind, and
you'll get *long* lists.
Find and steal the code for "char" (the real one-byte character type).
But a one-bit hash is what you really want, so it may be better to
implement your own.
