This is really a question for the DBD::Pg folks, I think. Looking at:
http://search.cpan.org/~turnstep/DBD-Pg-2.16.1/Pg.pm#COPY_support
It doesn't look like there is support for escaping COPY data. But
incidentally, I recently brought up the same problem with psycopg2 on
the psycopg list, and it seems there's no existing solution there,
either. Going out on a limb, I'm guessing that connectors don't offer
this support because there is no function in libpq for them to wrap,
and they don't want to kludge their own.
Anyone else think it might be a good idea for libpq to offer some
function to escape text to be used by COPY?
