I don't know what to do with that other than disabling COPY progress reporting for file_fdw, i.e. calls to BeginCopyFrom that don't supply a pstate. This is probably the best option, because a table backed by file_fdw would also interfere with COPY TO's progress reporting. Attached a patch that solves this specific issue in a binary-compatible way. I'm not super happy about relying on behavior of callers of BeginCopyFrom (assuming that users that run copy concurrently will not provide a ParseState* to BeginCopyFrom), but it is what it is. Kind regards, Matthias van de Meent
