I considered that, but it seemed like an abstraction violation to me,
because that code is part of xloginsert.c, which is mostly concerned
with assembly of write-ahead log records, not the associated
shared-memory state. Also, I don't think there's any guarantee that
the state in shared memory is initialized at the time we call that
function, so we might just be copying uninitialized memory into other
uninitialized memory.

Thanks, fixed.
