Besides also being pretty expensive it still wouldn't correct the clog -
and we don't always rely on hint bits.
I was thinking about just copying over the clog from the primary, but
it's not trivial if the standby isn't cought up, since the primary's
clog could have been truncated ahead of what the standby needs.
