Hi Jian, Thanks for the update.
I tried applying the v7 patch on current master (cbf9a72993e), but it doesn't apply cleanly. Most of the patch applies, however there are rejected hunks in src/backend/commands/copyfrom.c, src/backend/commands/tablecmds.c, and the fast_default regression test files. Could you please check if the patch needs a rebase or if there is a prerequisite patch? Regards, Solai
