Thanks for the clarification. I had added pg_fdw_xact_resolver() to resolve any transactions which can not be resolved immediately after they were prepared. There was a comment from Kevin (IIRC) that leaving transactions unresolved on the foreign server keeps the resources locked on those servers. That's not a very good situation. And nobody but the initiating server can resolve those. That functionality is important to make it a complete 2PC solution. So, please consider it to be included in your first set of patches.
The attached patch included pg_fdw_xact_resolver.
The attached patch includes the documentation.
