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. Best regards, Etsuro Fujita
