[Question] Cursor docs

Line 165 in ae5a89d

async with con.transaction():

Or, alternatively, you can iterate over the cursor manually (cursor won't be prefetching any rows):

async def iterate(con: Connection):
 async with con.transaction():
 # Postgres requires non-scrollable cursors to be created
 # and used in a transaction.

 async with con.transaction():
 # Create a Cursor object
 cur = await con.cursor('SELECT generate_series(0, 100)')

I don't undestand why nested transaction is necessary here. Can someone elaborate?

No reason. That was copy-paste. Thanks for noticing!
