28180837bf Allow pickling of cursor.description 
This is for people using dtuple.py; a dtuple.DatabaseTuple instance
keeps a reference to cursor.description, which is not picklable because
psycopg2 doesn't export the Column namedtuple it uses.

This commit exports the Column namedtuple, and includes a test to verify
the pickle/unpickle works after exporting Column.

0715771845 Dropped creation of errcodes with missing spec field 
On further inspection these names are just aliases for values already
defined: we don't need the duplication.

d232f25a68 Convert pool arguments to int 
Failing to do so may cause dangerous misbehaviours such as an unbounded
pool (because of lame comparison operators in Python 2).

Fix ticket #220.

They are used in the code but not defined in the SGML docs so the script
failed to parse them.

c10c1186a5 Added implementation for Range gt and ge operators 
Using a common implementation for all the operators. Note that lt is the
one used by sort so it's nice it's the fastest.

f739576f0a Provide a stable and consistent sort order for Range objects. 
This matches postgres server-side behaviour and helps client applications that need to sort based on the primary key of tables where the primary key is or contains a range.

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.

'public' if the schema is not specified.
