0001 has a mistake here, no? The initial control file creation goes
through WriteControlFile(), and not update_controlfile(), so this
change means that we would miss setting up this timestamp for the

This one had better not be removed, either, as we require pg_resetwal
to guess a set of control file values. Removing the one in
RewriteControlFile() is fine, on the contrary.
