OK. I could apply PG10's patch to 9.6.
Also, I've made a separate patch for 2PC description.

On the other hand, I need to mention that
there are some gaps to cause failures to apply patches
between supported versions.
(e.g. applying a patch for HEAD to stable PG13 fails)

To address the gaps between the versions,
I needed to conduct some manual fixes.
Therefore, please note that the content of patch
between PG12 and PG13 are almost same
like PG9.6 and PG10, but, I prepared
independent patches for HEAD and PG11,
in order to make those applied in a comfortable manner.

Kindly have a look at the updated patch-set.
They all passed the test of make html.
