How to use the batch delete feature in pgsql?

In PostgreSQL, you can use the DELETE statement to delete data in bulk. To delete data in bulk, you can use the WHERE clause to specify the conditions of the data you want to delete. Here is a simple example:

DELETE FROM table_name WHERE condition;

In the example above, table_name represents the name of the table from which data is being deleted, and condition indicates the criteria that need to be met. By specifying the condition in the WHERE clause, all data that satisfies the condition can be deleted.

To delete all data from a table, you can use the following statement:

DELETE FROM table_name;

Please be aware that before executing the DELETE statement, make sure you have backed up your data or confirmed that the data you want to delete is correct, as the delete operation is irreversible.
