In 8.2 there is a built in int --> bool cast. I had a similiar problem with
8.0 and I created my own int::bool cast using the following:
CREATE CAST (int4 AS bool)
WITH FUNCTION bool(int4)
AS ASSIGNMENT;
CREATE OR REPLACE FUNCTION bool(int4)
RETURNS bool AS
$Body$
Declare
output char(1);
Begin
Select into output $1;
Return output;
End;
$Body$
LANGUAGE 'plpgsql' VOLATILE;
This way I did not have to include the casting in SQL statements. Be aware
that if you upgrade to 8.2 the restore process will weed out the above
because of the builtin cast.
