- I got this error from mattermost.log after migrate from mysql 8.0 to postgresql.

```auto
..."level":"error","msg":"searchBoardsForUserInTeam ERROR","caller":"app/plugin_api.go:1130","plugin_id":"focalboard","error":"\"pq: could not identify an equality operator for type json\""}

```

- I’m using mattermost 10.11.17. Do anyone know if I should change all the json columns to jsonb, or other solution?
