Previously, libpq and the backend had opposite ideas about whether it was necessary for the client to send a CopyDone message after receiving an ErrorResponse, making it impossible to cleanly exit COPY BOTH mode. Fix libpq so that works correctly, adopting the backend's notion that an ErrorResponse kills the copy in both directions. Adjust receivelog.c to avoid a degradation in the quality of the resulting error messages. libpqwalreceiver.c is already doing the right thing, so no adjustment needed there. Add an explicit statement to the documentation explaining how this part of the protocol is supposed to work, in the hopes of avoiding future confusion in this area. Since the consequences of all this confusion are very limited, especially in the back-branches where no client ever attempts to exit COPY BOTH mode without closing the connection entirely, no back-patch. |
