Full page writes

It occurs to me that we don't need to write full page writes on newly extended
pages. Is that optimization in the code already? I would check except I'm not
even sure where to look for it.

Look for XLOG_HEAP_INIT_PAGE ... I suspect there are other cases where
the idea could be applied, but at least the basic first-heap_insert
scenario is covered.
