What is the process for removing all data from PostgreSQL where the JSONB field includes an array of keys?

edit

The process for removing all data from PostgreSQL where the JSONB field includes an array of keys would involve using the DELETE command with a WHERE clause that specifies the condition for the JSONB field.

Here is an example query that removes all data from a table called "mytable" where the JSONB field "myfield" includes an array of keys:

DELETE FROM my_table WHERE my_field -> 'my_array' ?| array['key1', 'key2'];

In this query, the -> operator is used to access the "myarray" field within the "myfield" JSONB object. The ?| operator checks whether any of the keys in the specified array (in this case, "key1" and "key2") are present in the "my_array" field.

This query will delete all rows from the "mytable" table where the "myfield" JSONB field includes an array that contains at least one of the specified keys.
