PostgreSQL INSERT into an array of enums

Question

How can I insert an array of enums?
Here is my enum:

CREATE TYPE equipment AS ENUM (\'projector\',\'PAsystem\',\'safe\',\'PC\',\'ph         


        

Answer 1

Additionally to @harm answer, you can skip quotations marks:

INSERT INTO lecture_room (equipment) VALUES ('{projector, safe}');

Answer 2

Old question, but a new answer. In modern versions of Postgres (tested with 9.6) none of this is required. It works as expected:

INSERT INTO lecture_room (equipment) VALUES ('{"projector", "safe"}');

Answer 3

The alternative to an ARRAY constructor like @Mark correctly supplied is to cast a string literal directly:

'{projector,PAsystem,safe}'::equipment[]

This variant is shorter and some clients have problems with the ARRAY constructor, which is a function-like element.

Answer 4

PostgreSQL doesn't know how to automatically cast input of type text to input of type equipment. You have to explicitly declare your strings as being of type equipment:

ARRAY['projector','PAsystem','safe']::equipment[]

I confirmed this with SQL Fiddle.
