Question, with this option if the power goes out will I just roll 
through the transaction logs like normal? Or are we talking the 
potential to have to use something like pg_resetxlog or similar?

If it is just roll through the transaction logs then I have no problem 
with it, let the user decide the level of reliance they have. If it can
cause actual, need to restore from backup level damage then it is a 
literall no go IMHO.
