Re: New "raw" COPY format

Hi,

Idle thoughts from a design perspective -- feel free to ignore, since
I'm not the target audience for the feature:

- If the column data stored in Postgres contains newlines, it seems
like COPY TO won't work "correctly". Is that acceptable?
- RAW seems like an okay-ish label, but for something that's doing as
much magic end-of-line detection as this patch is, I'd personally
prefer SINGLE (as in, "single column").
- Speaking of magic end-of-line detection, can there be a way to turn
that off? Say, via DELIMITER?
- Generic DELIMITER support, for any single-byte separator at all,
might make a "single-column" format more generally applicable. But I
might be over-architecting. And it would make the COPY TO issue even
worse...

Thanks,
