b04bf41f99 Fixed decimal to float recipe to avoid using FLOAT. 
FLOAT seems not working with NULLs.

bf1c76b792 Explicit cast of the SQL representation of time-related objects. 
Allow the objects to be recognized as the proper type by Postgres in not
strong contexts: problem reported by Peter Eisentraut.

Added tests to check the types are respected in a complete Py -> PG ->
Py roundtrip without context.

c8aef26e15 Adapt buffer objects using an explicit cast on the string literal. 
Don't rely on Postgres casting the literal according to the context:
this doesn't work e.g. passing the object as function argument where a
function with the same name but taking a text exists. It doesn't work
either when the object is in an ARRAY construct.

Added test to check the type is respected in a complete Py -> PG -> Py
roundtrip without context.

Bug and solution reported by Peter Eisentraut.

73db6bee01 Keep the connection in blocking mode unless it is not async. 
Dropped set/unset nonblocking mode for copy and lobject operations:
lobjects don't work in nonblocking mode so they will hardly be supported
in green/async branches.  Support for copy is still feasible, but it
will be done in other code paths (called by poll).

e29424a230 Dropped large object support when psycopg is in green mode. 
Async mode and large object are not compatible, albeit I haven't found
an authoritative source yet.

1edbd16577 Dropped curs_get_last_result function. 
The result is read from a pqpath function and put on the async_cursor by
a function that also checks for is presence and dismiss it after its
usage.

a66de9808f Added 'pq_get_last_result()' function. 
The function reads the last result after an asynchronous query.

5be0fc52ca Reusable parts of the green polling refactored out. 
The functions _conn_poll_connecting() and _conn_poll_query() will be
usable by the async connections too.

9f5d835de6 Functions conn_poll_* renamed to conn_poll_connect_*.

afterwards.

7af0bf0b54 Set the async_status to ASYNC_DONE after a query with wait callback. 
Failing in doing that broke notifications reception.

The responsibility for changing the async_status has been moved to the
poll function: this is consistent with how the async branch is
implemented.

With this commit all the test suite passes in "green" mode.

8fed0aa57d Forbid COPY-related methods in green mode. 
With the current implementation, at best they would silently block. They
actually hang everything.

Implementation posponed after some refactoring of the polling system,
because it will be probably possible to provide an implementation for
'poll()' during COPY which is good for both async and green modes.

0ec73a18b4 'pq_execute_command_locked()' calls the wait callback if set. 
The function is called without holding the GIL. Because it is necessary
to execute the Python callback if set, we need to re-acquire the GIL and
tnen release it again. In order to correctly bookkeep the thread state,
the pointer of the _save variable is passed to the function.

1607f89bb1 Avoid the locks dance when reading the connection socket number. 
It is a fast and non critical operation, so the lock is not required.
Furthermore, called from the wait callback creates a deadlock.

Added tests for basic notifications process.

12ef826d50 Dropped redundant call to conn_notice_process(). 
If the connection is sync, notices will be processed by pq_fetch()
downstream.

If the connection is async, here we have only sent the query: no result
is ready yet, and neither notices have had a chance to arrive: they will
be retrieved later by pq_is_busy().

Added tests to check the above statement don't break.
