Subject: (non)zero function
Date: Sun, 27 Mar 2005 17:58:07 +0200

Hi folks,


is there an function returning true if the argument is null or 
zero (just to make some queries more concise). Of course its 
trivial to implement as SQL function, but if postgresql already
provides such a function, I would prefer using it.
