Hi Team

As one issue(*https://github.com/psycopg/psycopg2/issues/781
<https://github.com/psycopg/psycopg2/issues/781>*) has already been created
for conn.poll() function hangs when executes COPY command in async mode.
Similarly conn.poll() functions hangs when we run wrong query in async mode
using sshtunnel <https://pypi.org/project/sshtunnel/; v0.1.3.

Can someone please suggest what went wrong when used sshtunnel, or the
pointers/reason where poll() method hangs.
