048f1bb95a Remove workaround for decimal module 
The decimal module is available on all Python versions supported by
psycopg2. It has been available since Python 2.4. No need to catch an
ImportError.

d58844e548 Clean up JSON workarounds for unsupported Python versions 
All Python versions supported by psycopg2 have the json module. It was
added in Python 2.6. Can remove checks for availability, slightly
simplifying the code.

05c28cce78 Remove workarounds for namedtuple on Python <= 2.5 
namedtuple is available on all Python versions supported by psycopg2. It
was first introduced in Python 2.6. Can remove all workarounds and
special documentation.

390e43fcb1 Use modern except syntax throughout project 
The syntax "except Exception, exc:" is deprecated. All Python versions
supported by psycopg2 support the newer, modern syntax. Forward
compatible with future Python versions.

make it stays so.

61e52ce879 Rework replication protocol

case of a synchronous connection.

A number of other changes and fixes are put into this commit.

e32e1b834e Add support for streaming replication protocol 
Introduce ReplicationConnection and ReplicationCursor classes, that
incapsulate initiation of special type of PostgreSQL connection and
handling of special replication commands only available in this special
connection mode.

The handling of stream of replication data from the server is modelled
largely after the existing support for "COPY table TO file" command and
pg_recvlogical tool supplied with PostgreSQL (though, it can also be
used for physical replication.)

doesn't want to get into all the details of parsing a dsn string:
quoting, URL format, etc.

5af5fb4cc6 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.
