DROP TABLE foo,bar,baz;

如果你真的需要一个脚爪，这一个会做它的工作：

CREATE OR REPLACE FUNCTION footgun(IN _schema TEXT,IN _parttionbase TEXT) 
RETURNS void 
LANGUAGE plpgsql
AS
$$
DECLARE
    row     record;
BEGIN
    FOR row IN 
        SELECT
            table_schema,table_name
        FROM
            information_schema.tables
        WHERE
            table_type = 'BASE TABLE'
        AND
            table_schema = _schema
        AND
            table_name ILIKE (_parttionbase || '%')
    LOOP
        EXECUTE 'DROP TABLE ' || quote_ident(row.table_schema) || '.' || quote_ident(row.table_name);
        RAISE INFO 'Dropped table: %',quote_ident(row.table_schema) || '.' || quote_ident(row.table_name);
    END LOOP;
END;
$$;

SELECT footgun('public','tablename');
