I think there's a snag in the patch:
postgres=# COPY data FROM '/Users/jwp/DATA.bcopy' WITH BINARY;
ERROR: row field count is -1, expected 1
CONTEXT: COPY data, line 4
Probably a quick/small fix away, I imagine.
But, I was able to trigger the new ERROR with py-postgresql:
>>> import postgresql as pg
>>> db=pg.open('localhost/postgres')
>>> q=db.prepare('copy data FROM STDIN WITH BINARY')
>>> from itertools import chain
>>> import sys
>>> db.pq.tracer = sys.stderr.write
>>> q.load_rows(chain(open('/Users/jwp/DATA.bcopy', 'rb'), (b'EXTRA',)))
