<b>to produce:</b><br>

create table test (num varchar(20));<br>

insert into test (num) values (null);<br>
select * from test where cast(num as int8) = 0; --ok, no error<br>
insert into test (num) values ('123123');<br>
select * from test where cast(num as int8) = 123123; --ok, no error<br>
<br>
insert into test (num) values (' ');<br>
select * from test where cast(num as int8) = 123123; -- error<br>
select * from test where case when trim(num) <> '' then cast(num
