This still makes catching up in standby mode slower, as you get many
more restartpoints. The reason for ignoring checkpoint_segments during
recovery was to avoid that. Maybe it's still better than what we have
currently, I'm not sure, but at least it needs to be discussed. Would be
good to do some performance testing of recovery with various
checkpoint_segments and _timeout settings, with and without this patch.
