Public bug reported:
We use the same function "check_key_parts" for all checks related to keys.
This produces a confusing error message when a key is partial, but in the
context where partial keys are allowed.
For example, box.select(0) when the primary key is TREE, returns all keys.
The same on a HASH primary key returns error "Partial key in exact match"
(ER_EXACT_MATCH).
If partial_key_allowed is taken from index traits, we should say
something like:
Hash indexes don't support search by a partially specified key
This would be less confusing.
Not fixing it right away since there is work in progress in this part of
the code.
