The assumption was that we would only want an additional level for
catching can't-happen conditions. ISTM this is not true. Consider an
out of memory error: do we want to only rollback the affected
subtransaction, or the whole transaction tree? If we want the latter we
will have to invent a new elevel.
In fact, I think we should mark ERROR as aborting the whole transaction
tree, and create a new level which would abort the innermost
subtransaction. We would then change whatever is appropiate to the new
elevel. Doing otherwise would leave us open to unexpected conditions
causing only subtrans abort, which could lead to unreliable behavior.
In short, I think all elog(ERROR) should have different behaviour from
ereport(ERROR), at least. And I don't think the answer should be
elog(FATAL) for the former.
