insert values to array column in PostgreSQL

Question

I have table "details" with the below structure

id     status1      status2    names
 1    approved     rejected     NULL
 2    approved     rejected     NULL
 3    approved     rejected     NULL
 4    rejected     rejected     NULL

I want to insert values to array column "names" with default values {john,smith}

example :I need

  id     status1      status2    names
   1    approved     rejected   {john,smith}
   2    approved     rejected   {john,smith}
   3    approved     rejected   {john,smith}
   4    rejected     rejected   {john,smith}

It fails when i wrote

INSERT INTO details (names) VALUES(ARRAY['john', 'smith']);

Answer 1

If you want to keep existing values with new ones:

UPDATE details SET names = names || '{john, smith}';
