Question: with the new syntax, would issuing a BEGIN inside a already
started transaction result in an error?
My concern is about say, a pl/pgsql function that opened and closed a
transation. This could result in different behaviors depending if
called from within a transaction, which is not true of the old syntax.
Then again, since a statement is always transactionally wrapped, would
it be required to always issue SUBBEGIN if issued from within a
function? This would address my concern.
