BTW, after further study of the SQL spec we concluded that we still didn't have it quite right. 7.3 will throw an error only during implicit coercion to char(N) or varchar(N); an explicit coercion will silently truncate. For example: update foo set varchar4col = '12345'; -- throws error update foo set varchar4col = '12345'::varchar(4); -- stores '1234' Dunno if this will help either of you at this point; you've probably already changed your apps to not need it. >> And yet, what is the Right Way to deal with timestamp? > Try, for example, replacing "timestamp" with datetime in the query you > showed me. Datetime is an obsolete alias for timestamptz ... it will go away in 7.3, so I'd recommend not using it now ... regards, tom lane
