Sorry, misremembered the problem somewhat. The problem is that code that
includes postgres.h atm ends up with ExceptionalCondition() et
al. declared even if FRONTEND is defined. So if anything uses an assert
you need to provide wrappers for those which seems nasty. If they are
provided centrally and check for FRONTEND that problem doesn't exist.
