I don't see the point of changing StartupCLOG() to be an empty
function and adding a new function TrimCLOG() that does everything
StartupCLOG() used to do.  Seems simpler to just move the calls to
StartupCLOG() wherever they need to be - i.e. remove the one that
happens before WAL replay, and extricate the one at end-of-recovery
from the if block which currently contains it.
