Hello, I'm a bit new to PostgreSQL, and I have a question about user-defined types. Is it possible to have an array of user-defined types? Suppose the type looks like this: CREATE TYPE part AS (id int2, count int2); Now I want to have a column in a table that is a list of parts: alter table items add column part_list part[]; But when I try to execute this statement, I get the error that "part[]" is not a defined type. Is it not possible to have an array of user-defined types?
