Thomas, Andrew, Karel,

Thomas is correct: many applications which read or make CSVs will accept a 
newline if it is enclosed in a quote.

This I have never seen.   It looks like a hackish error to me.   What 
application is it from?

Frankly, I would expect any CSV reader to error out on the above, and would be 
annoyed if it did not.

Overall, I assert again that approaching this issue through COPY enhancements 
is really not the way to go.    We should be looking at a client utility, 
like pg_import and pg_export.     The primary purpose of COPY is bulk loads 
for backup/restore, and I'm against doing a lot of tinkering which might make 
it less efficient or introduce new issues into what's currently very 
reliable.
