Answer 1

Heroku 的 Dataclips似乎是 designed for viewing data ，不修改它:

A Dataclip is a secret URL that holds the results of a SQL query on a particular Heroku Postgres database. Given the unique, private URL for a query, a user can call up the most recently stored results of that query. Our system will automatically re-run the Dataclip from time to time in order to keep results fresh. By sharing a Dataclip URL the same way you would share the underlying data, any recipient can view that data within, download it as a CSV, or even embed it live into a tool like Google Sheets.

很可能您无法使用此工具修改数据。

如果您只是想插入一些数据，请使用常规数据库客户端。
