I've tried pg8000 and was able to use it to dump a few hundred gigs
out of an existing PostgreSQL DB with COPY with zero issues. I haven't
done much in the way of other SQL, and I contributed the (small) patch
to add COPY support, but it was on top of existing code that looked
good. In contrast, I have had very bad experiences with psycopg2's
COPY support in the past.

Just because one person failed to properly implement the PostgreSQL
protocol doesn't mean that all people have failed :) There are
actually maybe four or five different ones out there, but pg8000 is
the best of breed. I'm a lot more likely to trust a pure Python
implementation than something in C; if there's a problem it's a heck
of a lot easier to fix in Python.
