Description: aiopg
        =======
        
        **aiopg** is a library for accessing a PostgreSQL_ database
        from the asyncio_ (PEP-3156/tulip) framework. It wraps
        asynchronous features of the Psycopg database driver.
        
        Example
        -------
        
        ::
        
           import asyncio
           from aiopg.pool import create_pool
        
           dsn = 'dbname=jetty user=nick password=1234 host=localhost port=5432'
        
        
           @asyncio.coroutine
           def test_select():
               pool = yield from create_pool(dsn)
        
               with (yield from pool) as conn:
                   cur = yield from conn.cursor()
                   yield from cur.execute('SELECT 1')
                   ret = yield from cur.fetchone()
                   assert ret == (1,), ret
        
        
           asyncio.get_event_loop().run_until_complete(test_select())

        -------------------------------------------
        
        ::
        
           import asyncio
           from aiopg.sa import create_engine
           import sqlalchemy as sa
        
        
           metadata = sa.MetaData()
        
           tbl = sa.Table('tbl', metadata,
           sa.Column('id', sa.Integer, primary_key=True),
           sa.Column('val', sa.String(255)))
        
        
           @asyncio.coroutine
           def go():
               engine = yield from create_engine(user='aiopg',
                                                 database='aiopg',
                                                 host='127.0.0.1',
                                                 password='passwd')
        
               with (yield from engine) as conn:
                   yield from conn.execute(tbl.insert().values(val='abc'))
        
                   res = yield from conn.execute(tbl.select())
                   for row in res:
                       print(row.id, row.val)
