How do I insert multiple values into a postgres table at once?

Question

I have a table that I am trying to update multiple values at once. Here is the table schema:

    Column     |  Type   | Modifiers  ---------------+---------+-----------  user_id       | integer |   subservice_id | integer | 

I have the user_id and want to insert multiple subservice_id's at once. Is there a syntax in Postgres that will let me do something like this

insert into user_subservices(user_id, subservice_id) values(1, [1, 2, 3]); 

How would I do this?

Answer 1

Multi-value insert syntax is:

insert into table values (1,1), (1,2), (1,3), (2,1); 

But krokodilko's answer is much slicker.
