SQLAlchemy 文档解释了如何创建分区表。但它没有解释如何创建分区。

所以如果我有这个：

#Skipping create_engine and metadata
Base = declarative_base()

class Measure(Base):
    __tablename__ = 'measures'
    __table_args__ = {
        postgresql_partition_by: 'RANGE (log_date)'
    }
    city_id = Column(Integer, not_null=True)
    log_date = Columne(Date, not_null=True)
    peaktemp = Column(Integer)
    unitsales = Column(Integer)

class Measure2020(Base):
    """How am I suppposed to declare this ? """

我知道我会做的大部分事情SELECT * FROM measures WHERE logdate between XX and YY。但这似乎很有趣。
