Answer 1

The documentation says:

The || operator concatenates the elements at the top level of each of its operands. ... For example, if both operands are objects with a common key field name, the value of the field in the result will just be the value from the right hand operand.

So using your example data:

update table_name set
  data = data || '{"city": "ottawa", "phone": "phonenum", "prefix": "prefixedName"}'
where number = 1;

Additionally if the object you want to edit is not at the top level - just combine the concatenation and jsonb_set function. For example, if the original data looks like

{"location": {"name": "firstName", "city": "toronto", "province": "ON"}}

then

...
data = jsonb_set(data, '{location}', data->'location' || '{"city": "ottawa", "phone": "phonenum", "prefix": "prefixedName"}')
...
