Postgres 9.2.4.
I have two columns, approved and comments. Approved is a boolean with no
default value and comments is a character varying (255) and nullable.
I am trying to create a constraint that will not allow a row to be entered
if approved is set to false and comments is null.
This does not work. yada, yada, yada... add constraint "chk_comments' check
(approved = false and comments is not null). The constraint is successfully
added, but does not work as I expected.
