How to convert integer to boolean in insert - Mailing list pgsql-general

for table
foo
  banned:boolean

When try  run 'insert into foo(banned) values(0)'
It returns
ERROR:  column "banned" is of type boolean but expression is of type
integer
LINE 1:  insert into foo(banned) values(0)

and I found a way to add the cast
insert into foo(banned) values(0::boolean)
but I have a big table which dump from mysqldump and covert by
mysql2pgsql. all of boolean relation values is 0 instead of '0' or
FALSE.

Is there any way to make pgsql implicit cast the integer to boolean?

Thanks
