        **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
            import aiopg
        
            dsn = 'dbname=aiopg user=aiopg password=passwd host=127.0.0.1'
        
            async def go():
                pool = await aiopg.create_pool(dsn)
                async with pool.acquire() as conn:
                    async with conn.cursor() as cur:
                        await cur.execute("SELECT 1")
                        ret = []
                        async for row in cur:
                            ret.append(row)
                        assert ret == [(1,)]
        
            loop = asyncio.get_event_loop()
            loop.run_until_complete(go())

           tbl = sa.Table('tbl', metadata,
               sa.Column('id', sa.Integer, primary_key=True),
               sa.Column('val', sa.String(255)))

                                             val varchar(255))''')
