That's what pgloader does to allow for non-quoted fields containing
escaped separator in some contrived input formats (UNLOAD from Informix,
I'm looking at you).
I guess the same kind of playing could be applied to CSV too, but it'd
be necessary to search back to the previous \n and count the QUOTE chars
you find. Which does not sound like a huge win, even if you remember the
state at the last quoted \n.
Fancy format parsing ain't fun.
