This could be an issue of compression, perhaps you are storing the data uncompressed in Postgres.这可能是压缩问题，也许您将未压缩的数据存储在 Postgres 中。 Unfortunately Postgres only supports "TOAST" compression for rows that are above 2000 bytes.不幸的是，Postgres 只支持对超过 2000 字节的行进行“TOAST”压缩。 If your data has rows that are smaller than that, they won't get compressed, which will lead to much larger data volumes, like you are experiencing.如果您的数据的行小于此值，则它们不会被压缩，这将导致更大的数据量，就像您正在经历的那样。

You may want to consider a different storage database, that supports compression, if minimizing data size is of utmost importance.如果最小化数据大小至关重要，您可能需要考虑支持压缩的不同存储数据库。 Perhaps a SQL Server hosted on AWS?也许是托管在 AWS 上的 SQL 服务器？
