Answer 1

You should be use jsonb to store JSON data in your table.

CREATE TABLE customer {
  contact JSONB
}

Example(Object):- Insert Object JSON Value

Insert into customer(contact )
Values('{ "phones":[ {"type": "mobile", "phone": "001001"} , {"type": "fix", "phone": "002002"} ] }')

Example(Array):- Insert array JSON Value

Insert into customer(contact )
Values('[ {"type": "mobile", "phone": "001001"} , {"type": "fix", "phone": "002002"} ]')
