This is why I proposed originally to keep the non-transactional behavior
for Parse messages, but transactional for SQL PREPARE. The latter can
be said to be inside the transaction and should behave like so. I think

Bob [Floyd] used to say that he was planning to get a Ph.D. by the "green
stamp method," namely by saving envelopes addressed to him as 'Dr. Floyd'.
After collecting 500 such letters, he mused, a university somewhere in
Arizona would probably grant him a degree. (Don Knuth)
