Hi After truncate the table, the oid retuned by PQftable/libpq returns the old value, and i'm not able to find it in pg_class, because the value of pg_class.relfilenode was changed after the truncate.
The problem is only solved if i drop the table and re-creating again. Regards Rodrigo Moreno ---------------------------(end of broadcast)--------------------------- TIP 8: explain analyze is your friend
