bca7200b3f Cache FixedOffsetTimezone instances
Avoid creating new a new FixedOffsetTimezone instance if one with the
same offset and name has been created before. This will save memory
when returning many rows containing "timestamp with timezone" columns,
and also improves comparability.

1469a56512 Fixed repr for FixedOffsetTimezone for offsets west of UTC (negative)
The offset displayed was always positive and somewhat confusing. The
offset displayed now is the offset that the instance was created
with.

Also added some tests for initialisation.

a4485022b5 Use 'autocommit' to check if to rollback after extra types registration
isolation_level currently requires an extra query, autocommit doesn't.

d2d94e203f Reverted isolation level values to backward compatible values
This basically removes the READ UNCOMMITED level (that internally
PostgreSQL maps to READ COMMITED anyway) to keep the numeric values
compattible with old psycopg versions. For full details and discussion
see this thread:

cb1d163f4f lazy import for uuid module
Attached patch moves uuid import from inside try-except
to register_uuid function.  Reason: uuid module import is *very*
heavy.  It goes into OS searching for various .dll/.so libraries,
lauches 'ldconfig' and so on...

With this patch, 200x python -c 'import psycopg2.extras'
goes from 22s to 7s.  (plain 'import psycopg2' is 6s)

5211e1474b Don't limit the hstore search to the public schema only
Looks like there is a case for installing hstore somewhere else (see
ticket #45). And after all the typecaster can be registered on a list of

fdfa2de1a1 Fixed adaptation of None in composite types (ticket #26).
Added an adapter for None: it is usually not invoked as adaptation to
NULL is a fast path in mogrify, but can be invoked by composite types.
Notice that composite types still have the option to fast-path None
(e.g. list adapter does).

01799e9137 Make asynchronous connections produce asynchronous cursors by default
Drop the async kwarg from cursor.execute(), cursors created by
asynchronous connections will be asynchronous by default, ones created
by synchronous connections will be synchronous.

Mind that this might break third party subclasses of
psycopg2.extensions.cursor, if they try to chain to the superclass in
their execute() implementation and are passing the async kwarg. The
example cursors in psycopg2.extras have been fixed no to do that.

34317dc4c3 Support asynchronous connection building

connection that will tell you whether its file descriptor should be
waited on to become writable or readable or that the connection
attempt has succeeded.
