With respect, sir, let me point out that Informix usage says to insert a zero to trigger a serial column, so don't be indicting Gustavo on MySQL use -- he might be coming from a real database where usage is different.
Those of us who came to postgres from Informix-land made [perhaps] the same mistakes. Not a bad *habit* unless you can prove to me that the spec says otherwise. (Maybe you can -- the SQL formal definitions seem to be deliberately opaque and often do not define _how_ a given behavior should be implemented). Just a matter of indoctrination into the local ways of doing serials.
