I think the basic part of this patch set is the following. The latter file unfortunately no longer applies to HEAD. v13-0001-Move-multi-insert-decision-logic-into-executor.patch v13_3-0002-Fast-COPY-FROM-into-the-foreign-or-sharded-table.patch Plus, as Tang-san said, I'm afraid the following files are older and doesn't apply. v9-0003-Add-separated-connections-into-the-postgres_fdw.patch v9-0004-Optimized-version-of-the-Fast-COPY-FROM-feature When do you think you can submit the rebased version of them? (IIUC at the off-list HighGo meeting, you're planning to post them late this week after the global snapshot patch.) Just in case you are not going to do them for the moment, can we rebase and/or further modify them so that they can be committed in PG 14? Regards Takayuki Tsunakawa
