I thought we had disposed of that argument. The issue here is not a
marginal efficiency gain, it is that an unresolved symbol will lead
to a backend crash (== database-wide restart) unless it is detected
at dlopen time. As a wise man once said, "I can make it arbitrarily
fast ... if it doesn't have to work."
