Should this not work?

No, because there's no built-in cast from smallint to bool.  You could
do something like

... type boolean using case when field1=0 then false else true end;

'k, I just took a read through the "CREATE CAST" man page, and don't think I can use that for this, but is there some way I can create a cast for this, so that we don't have to go through the complete application and change "VALUES ( 0 );" to "VALUES ( '0' );" ...

Again, from reading the man page, I'm guessing not, but just want to make sure that I haven't missed anything ...
