Hi there! I am using gino 1.0.1 and unfortunately, this project is no longer being updated. For migrating to Python 3.13 I install asyncpg 0.30.0 and found, that gino (await Model.insert().gino.all([{...}, {...}])] can't work with current version. Issue occurs when calling `bind_execute_many` Gino expects 4 arguments, but in version 0.30.0, a new argument `return_rows` was added.

How to gino using asyncpg:
```
def executor(state, timeout_):
if many:
return _protocol.bind_execute_many(state, args, "", timeout_)
else:
return _protocol.bind_execute(state, args, "", limit, True, timeout_)
```
My suggestion: add True as the default value for the `return_rows` argument:
``` @cython.iterable_coroutine
async def bind_execute_many(
self,
state: PreparedStatementState,
args,
portal_name: str,
timeout,
return_rows: bool = True,
)
```
