        **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
        -------
        
        .. code:: python
        
            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())
        
        
        Example of SQLAlchemy optional integration
        ------------------------------------------
        
        .. code:: python
        
           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)))
        
           async def create_table(engine):
               async with engine.acquire() as conn:
                   await conn.execute('DROP TABLE IF EXISTS tbl')
                   await conn.execute('''CREATE TABLE tbl (
                                             id serial PRIMARY KEY,
                                             val varchar(255))''')
        
           async def go():
               async with create_engine(user='aiopg',
                                        database='aiopg',
                                        host='127.0.0.1',
                                        password='passwd') as engine:
        
                   async with engine.acquire() as conn:
                       await conn.execute(tbl.insert().values(val='abc'))
        
                       async for row in conn.execute(tbl.select()):
                           print(row.id, row.val)
        
           loop = asyncio.get_event_loop()
           loop.run_until_complete(go())
