I think it is not commitfest ready yet -- I need to add some
documentation and tests first.
Yes, doc & test are missing.
From your figures, the murmur2 algorithm output looks way better. I'm
wondering whether it makes sense to provide a bad hash function if a
good/better one is available, unless the bad one actually appears in some
benchmark... So I would suggest to remove fnv1a.
One implementation put constants in defines, the other one uses "const
int". The practice in pgbench seems to use defines (eg
MIN_GAUSSIAN_PARAM...), so I would suggest to stick to this style.
I'm wondering whether "hash" should be a shorthand for one hash functions,
as a provided default chosen for its quality and efficiency.
