Hmm. This error is not coming from "a line of the copy", it is occurring
because the COPY command itself fails, and so the server never tells
psql to shift into COPY mode. I'm not sure that a reasonable fix for
this is possible. As a counterexample, if you misspelled COPY as COPZ,
would you expect the software to decide that following lines up to
\. should be ignored? If you manually misentered a COPY command and got
an error, would you be surprised to have psql ignore everything you
typed until you typed \. ? (I can bet we'd get bug reports about that.)
