I now have two tables named A and B. Table B is calculated based on the data of table A. I wonder if table B can be automatically deleted when table A is deleted？

Your question seems not that specific.

You can use https://dbfiddle.uk/btGcOH30 to showcase your specific problem/question.

you can use DROP TABLE CASCADE.

DROP TABLE manual: https://www.postgresql.org/docs/current/sql-droptable.html
