Previously heap_inplace_update_and_unlock() used an operation order similar to MarkBufferDirty(), to reduce the number of different approaches used for updating buffers. However, in an upcoming patch, MarkBufferDirtyHint() will switch to using the update protocol used by most other places (enabled by hint bits only being set while holding a share-exclusive lock). Luckily it's pretty easy to adjust heap_inplace_update_and_unlock(). As a comment already foresaw, we can use the normal order, with the slight change of updating the buffer contents after WAL logging.
