搜索Postgres JSONB字段

Question

I want to search the pattern '%myvalue%' in key and value for a json field, return any one that matched.

I use

select * from dialogue_responses where field_rule like '%myvalue%'

it prompts me error

LINE 1: select * from dialogue_responses where field_rule like '%auf...
                                                          ^

What's he correct way of doing this?

select * from dialogue_responses where field_rule::varchar like '%myvalue%'
