Update to PyGreSQL 3.1:

Fix some quoting functions. In particular handle NULLs better.

Use a method to add primary key information rather than direct
manipulation of the class structures.

Break decimal out in _quote (in pg.py) and treat it as float.

Treat timestamp like date for quoting purposes.

Remove a redundant SELECT from the get method speeding it, and
insert since it calls get, up a little.

Add test for BOOL type in typecast method to pgdbTypeCache class.

Fix pgdb.py to send port as integer to lower level function

Change pg.py to speed up some operations

Allow updates on tables with no primary keys.
