I'm using PostgreSQL 8.3.1.
I've created the following composite type:
CREATE TYPE expression_event_type AS (
event_id varchar(10),
expr_indices smallint[]
);
which is used with the following table definition:
CREATE TABLE boolean_expr_table(
expr_id smallint PRIMARY KEY,
expr_name varchar(100) NOT NULL,
expression varchar(256) NOT NULL,
event_indices expression_event_type[] NOT NULL,
true_cases smallint[] NOT NULL
);
Question: What is the correct way to load the event_indices column using the copy command and a external file?
I've tried: {(1,{1,2,3})} without success.
