pg_resetxlog doesn't know a single solitary thing about the clog.
The problem here is that if you're going to move the current xact ID
forward, you need to be prepared to create pages of the clog
accordingly. Or maybe the clog routines need to be less rigid in their
assumptions, but I'm uncomfortable with relaxing their expectations
unless it can be shown that they may fail to cope with cases that
arise in normal system operation. This isn't such a case.
