Hi,If it is jsonb type, you can have a look at the documentation : https://www.postgresql.org/docs/14/functions-json.html
There are some examples : |jsonb| |-| |text| → |jsonb|Deletes a key (and its value) from a JSON object, or matching string value(s) from a JSON array.
|'{"a": "b", "c": "d"}'::jsonb - 'a'| → |{"c": "d"}|
|'["a", "b", "c", "b"]'::jsonb - 'b'| → |["a", "c"]|
|jsonb| |-| |text[]| → |jsonb|
Deletes all matching keys or array elements from the left operand.
|'{"a": "b", "c": "d"}'::jsonb - '{a,c}'::text[]| → |{}|
|jsonb| |-| |integer| → |jsonb|
Deletes the array element with specified index (negative integers count
from the end). Throws an error if JSON value is not an array.
|'["a", "b"]'::jsonb - 1| → |["a"]| |jsonb| |#-| |text[]| → |jsonb|Deletes the field or array element at the specified path, where path elements can be either field keys or array indexes.
|'["a", {"b":1}]'::jsonb #- '{1,b}'| → |["a", {}]|
