Done. Attached is a new version.

This is an updated version of the previous patch. In addition to the
above, I expanded a comment in do_sql_command_end() a bit to explain
why we do PQconsumeInput() before doing pgfdw_get_result(), to address
your comment. Also, I moved the code to finish closing pending
(sub)transactions in pgfdw_xact_callback()(pgfdw_subxact_callback())
into separate functions. Also, I modified regression test cases a bit
to access multiple foreign servers.

This is a WIP patch for parallel abort. I added an option
parallel_abort for this, because I thought it would be good to
enable/disable these separately. I didn’t do any performance tests
yet.
Sorry for the long delay.
Best regards,
