d5d6a1f4c7 Enable by default the range typecasters 
Otherwise it would have been enabled importing psycopg2.extras,
which is a surprising behaviour.

27cd6c4880 Added specific pool implementation for ZPsycopgDA 
The implementation is based on psycopg 2.4, which should be less broken
(zope-wise) of the current one.

Instantiating psycopg2.pool.PersistentConnectionPool now raises a warning.

This should fix ticket #123, #125. The issue of the reset on
set_client_encoding() is still present but that's always been there and I'm no
good at fixing it.

20d3d0f66d Raise TypeError instead of InterfaceError on bad params on connect() 
TypeError is the standard Python error raised in this case:

    $ python -c "(lambda a: None)(b=10)"
    TypeError: <lambda>() got an unexpected keyword argument 'b'

We only used to raise InterfaceError when connect was used without
any parameter at all, so it's hard to think a program depending on
that design. Furthermore the function has always raised (and still
does) OperationalError too, if the bad argument is detected by the
libpq, and that cannot be changed because we can't tell the
difference from a normal connection error.

526e270934 Use namedtuple._make in NamedTupleCursor and CompositeCaster 
Makes things more natural as _make has the same signature of the tuple (see
_ctor in CompositeCaster) and is probably more efficient with less
intermediate sequences to build.

7386b8327c Dropped keywords passthrough in Json adapter 
Pass a dumps function instead. Allow customizing by either arg passing or
subclassing.

The basic Json class now raises ImportError on getquoted() if json is not
available, thus allowing using a customized Json subclass even when the json
module is not available.

095cce5605 Allow user to override connection factory cursors 
Prior to this change, using a extras.connection_factory would not allow
any other cursor to be used on that connection. It was set in stone.

This change allows all cursor options to pass through and override the
connection factory behaviors. This allows a connection_factory to be
dropped into existing code with no disruption.

This change also standardizes the extras.connection_factories to have
the same behavior and all pass through *args and **kwargs.

ebec522a07 Fixed rownumber for cursor subclasses during iterations 
Regression introduced to fix ticket #80. Don't use fetchmany to get the
chunks of values. I did it that way because I was ending up into infinite
recursion calling __iter__ from __iter__: the solution has been the
"while 1: yield next()" idiom.

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.

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)
