3bfbd3a0a5 Added test to verify sql objects work with copy_expert() 
I'll be honest: I lucked out, I didn't think about this combination. But
maybe sheer luck, maybe using common code paths, it just works. Let's
make it stays so.

12317557da Always raise OperationalError when connection was closed externally. 
From the DB-API (https://www.python.org/dev/peps/pep-0249/):

  OperationalError

  Exception raised for errors that are related to the database's
  operation and not necessarily under the control of the programmer,
  e.g. an unexpected disconnect occurs, [...]

Additionally, psycopg2 was inconsistent, at least in the async case:
depending on how the "connection closed" error was reported from the
kernel to libpq, it would sometimes raise OperationalError and
sometimes DatabaseError. Now it always raises OperationalError.

b203a7c775 Always detect when a connection is closed behind psycopg2's back. 
There's a race condition that only seems to happen over Unix-domain
sockets. Sometimes, the closed socket is reported by the kernel to
libpq like this (captured with strace):

  sendto(3, "Q\0\0\0\34select pg_backend_pid()\0", 29, MSG_NOSIGNAL, NULL, 0) = 29
  recvfrom(3, "E\0\0\0mSFATAL\0C57P01\0Mterminating "..., 16384, 0, NULL, NULL) = 110
  recvfrom(3, 0x12d0330, 16384, 0, 0, 0)  = -1 ECONNRESET (Connection reset by peer)

That is, psycopg2/libpq sees no error when sending the first query
after the connection is closed, but gets an error reading the result.
In that case, everything worked fine.

But sometimes, the error manifests like this:

  sendto(3, "Q\0\0\0\34select pg_backend_pid()\0", 29, MSG_NOSIGNAL, NULL, 0) = -1 EPIPE (Broken pipe)
  recvfrom(3, "E\0\0\0mSFATAL\0C57P01\0Mterminating "..., 16384, 0, NULL, NULL) = 110
  recvfrom(3, "", 16274, 0, NULL, NULL)   = 0
  recvfrom(3, "", 16274, 0, NULL, NULL)   = 0

i.e. libpq received an error when sending the query. This manifests as
a slightly different exception from a slightly different place. More
importantly, in this case connection.closed is left at 0 rather than
being set to 2, and that is the bug I'm fixing here.

Note that we see almost identical behaviour for sync and async
connections, and the fixes are the same. So I added extremely similar
test cases.

Finally, there is still a bug here: for async connections, we
sometimes raise DatabaseError (incorrect) and sometimes raise
OperationalError (correct). Will fix that next.

(almost... except for micros rounding)

While this is probably an improvement on the previous implementation,
I am largely waving a dead chicken at windows, which keeps failing to
pass the seconds overflow test. If it doesn't pass now either I'll start
blaming Python's timedelta.

Daniele Varrazzo
4a450b63c4 Don't hope to encode stuff in an arbitrary encoding 
libpq's PQescapeString will use the same encoding it has seen before in
a connection (static_client_encoding).

So I think I'll leave this feature here for people who know what is
doing, but won't really document it as a feature: it can't really work
in a generic way (unless adding some disgusting hack like creating a
fake connection with the encoding we want to call PQescapeStringConn
instead of PQescapeString).

bada1f1f8e Work in progress on writable encoding 
Would help using adapt(unicode) to quote strings without a connection,
see ticket #331.

Currently in heisenbug state: if test_connection_wins_anyway and
test_encoding_default run (in this order), the latter fail because the
returned value is "'\xe8 '", with an extra space. Skipping the first
test, the second succeed.

The bad value is returned by the libpq:

    ql = PQescapeString(to+eq+1, from, len);

just returns len = 2 and an extra space in the string... meh.
