I googled a lot
I'm using a tool ora2pg which takes the data in oracle and move it to postgres
in oracle this is a varchar(80 byte) field
PG
ref_property character varying(80),
ref_house character varying(80),
ref_object character varying(80)
so I don't know why it throws this exception
maybe I found something strange
the select lenght(ref_object) = 80
and the lengthb(ref_object) = 80
the field is varchar2(80 bytes)
strange is that the length and lengthb gives the same length
but ref_object has some special characters?
so how can the length be equal?
