If it's ok with you, I'd like to work on the performance issue.  What
I have in mind is commit all remote transactions in parallel instead
of sequentially in the postgres_fdw transaction callback, as mentioned
above, but I think that would improve the performance even for
one-phase commit that we already have.  Maybe I'm missing something,
though.
