Have you worked with the jsonb data type in a database?

Yes, the jsonb data type in PostgreSQL is a binary representation of JSON that allows efficient storage and indexing of JSON data.

In Go, working with jsonb typically involves using the database/sql package along with a PostgreSQL driver (such as lib/pq or pgx). To pass and retrieve data in a jsonb field, types like []byte or string are used, as well as structures that are serialized/deserialized using the encoding/json package.

Example of writing a structure to a jsonb field:

import (
    "database/sql"
    "encoding/json"
    _ "github.com/lib/pq"
)

type Data struct {
    Name string `json:"name"`
    Age  int    `json:"age"`
}

func insertJSONB(db *sql.DB, d Data) error {
    jsonData, err := json.Marshal(d)
    if err != nil {
        return err
    }
    _, err = db.Exec("INSERT INTO table_name (jsonb_column) VALUES ($1)", jsonData)
    return err
}

Thus, working with jsonb involves serializing structures into JSON, storing them in a jsonb field, and then querying and deserializing them.
