Hi, I need a unique ID across all columns I create. Is it o.k. to achive this by combining pg_attribute.attnum of a column together with the OID of the table the column is in?
While the table's OID should be unique according to the manual, I have found no hints about the uniqueness of attnum -- I removed and added some columns and it seems that already used values are not used again.
