Essentially agreed, but I think it's excusable for SQLite as a 
light-weight database to make an exception here so that it can be used 
easily and directly from the standard lib without the need to install 
any additional higher level wrapper.

To wrap everything up, as a result of our discussion, I will do the 
following in the next version of PyGreSQL:

* make connections context managers for transactions
   (may not be the optimal solution, but it's already established)
* make cursors self-closing context managers (evident)
* not implement shortcut functions (see above)

Is everybody happy with that?
