Well, I agree that losing regression testing of the feature would be a
Bad Thing. But we already require superuser privs to run the regression
tests. I'm thinking if we were to change things so that the regression
tests could temporarily turn on the ability to issue PREPARE
TRANSACTION, it would be possible to keep the testing but still have
the out-of-the-box configuration disable PREPARE TRANSACTION.
Anyway, as I said originally, this is all just brainstorming at this
point.
