fastapi contrib有postgresql的paginator吗？

# 创建数据库连接
SQLALCHEMY_DATABASE_URL = "postgresql://username:password@localhost/dbname"
engine = create_engine(SQLALCHEMY_DATABASE_URL)
SessionLocal = sessionmaker(autocommit=False, autoflush=False, bind=engine)
Base = declarative_base()

# 定义数据库模型
class Item(Base):
    __tablename__ = "items"
    id = Column(Integer, primary_key=True, index=True)
    name = Column(String, index=True)

# 创建FastAPI应用
app = FastAPI()

# 获取数据库会话
def get_db():
    db = SessionLocal()
    try:
        yield db
    finally:
        db.close()

# 定义分页查询接口
@app.get("/items/")
def read_items(skip: int = 0, limit: int = 10, db: Session = Depends(get_db)):
    items = db.query(Item).offset(skip).limit(limit).all()
    return items

# 运行FastAPI应用
if __name__ == "__main__":
    uvicorn.run(app, host="0.0.0.0", port=8000)
