I don't understand why you need a column per variable.

I'd use something like

CREATE TABLE configuration_settings
(
variable_name text primary key not null,
variable_value text
);

INSERT INTO configuration_settings
(variable_name, variable_value)
VALUES
('myfirstvar', 'Some value');

INSERT INTO configuration_settings
(variable_name, variable_value)
VALUES
('mysecondvar', 'Another value');
