在Postgresql数据库的列中插入两个或三个值

Question

there is postgresql database named movie_db, and created a table named films as following:

CREATE TABLE movies (
title       varchar(128) NOT NULL,
description varchar(256) NOT NULL,
directors   varchar(128)[],
roles       varchar(128)[]
);

I want to insert the following data:

title   description          directors     roles
a       the love of wind      tom       tom, kaon, kate 
b       the second way story  john      jack, mark 

for example, you know the movie has not just one actor, for example, movie has the actor(roles): tom, kaon, and kate. I want to insert these two data into the table using the following command:

insert into movies(title, description, directors, roles) values('a',    
'the love of wind', 'tom',{'tom, kano, kate'}))

but there is error:

 ERROR:  syntax error at or near "{"
 LINE 1: ...ors, roles) values('a', 'the love of wind', 'tom',{'tom,   
 kan..
                                                         ^

Could you help me to deal with it, thanks for your help!

Answer 1

Thanks@a_horse_with_no_name, I solved it, after I read the document about array in the postgresql document.

The answer about my issue posed:

insert into movies(title, description, directors, roles) values('a',     
'the love of wind', '{"tom"}','{"tom", "kano", "kate"}');
