> For example, the boolean type in PostgreSQL will accept TRUE, 'true', 't', '1', 'on', 'y' and 'yes' (case insensitive) for truthful values and the equivalents for false values. But does it support 'affirmative', 'correct', 'aye' (http://thedailywtf.com/Articles/Are-You-Sure.aspx http://thedailywtf.com/Articles/Are-You-Sure.aspx) or 'YOUBET', 'YEP', 'NOWay', 'YEAH', 'NOPE', 'Maybe' (http://thedailywtf.com/Articles/The-Object-Test,-a-New-PI,-and-More-SHEEIT.aspx http://thedailywtf.com/Articles/The-Object-Test,-a-New-PI,-a...) ? Note the mapping of 'Maybe' to a boolean through '__TIME__[7]&1'!
