Thread: add a value to an ENUM type

add a value to an ENUM type

From
Edoardo Panfili
Date:
I have an enum type
CREATE TYPE shapeName AS ENUM('rectangle','circle');

now I need another value: 'square'

the pg_type.oid of 'shapename is 16458

It works, but Is it safe to use this?
insert into pg_enum (enumtypid,enumlabel) VALUES('16458','square');

thank you
Edoardo

I have done this previously on several occasions to modify ENUM
values, so it will work. However, when I inquired about doing the
same, I was told "be careful and be sure of what you're doing", so
I'll forward it on to you as well.

thank you,
I forgot to say that for me sorting order is not important on this type.
