如何在postgresql的列表分区中存储其他值

CREATE TABLE parent_table (
    id SERIAL PRIMARY KEY,
    category TEXT,
    value TEXT
);

CREATE TABLE child_table_category1 PARTITION OF parent_table
    FOR VALUES IN ('category1');

CREATE TABLE child_table_category2 PARTITION OF parent_table
    FOR VALUES IN ('category2');

INSERT INTO child_table_category1 (category, value)
VALUES ('category1', 'value1');

INSERT INTO child_table_category2 (category, value)
VALUES ('category2', 'value2');

SELECT * FROM parent_table WHERE category = 'category1';
