Cannot the UTF8-translated SQL text (which is currently inside
Statement::sqlText) be the key, to avoid dependency on the charset? I don't
think that semantically different statements may have the same UTF8
representation. However, it would make sense to have a single cached statement
for the same statement executed from different client charsets.
Only if such translation is made right. Remember charset introducers.
But apparently to transform the query before using it as a cache key is a
right idea. Two queries different only by some whitespaces, comments or case
(unless in literals) should not miss the cache.
