bug or feature, || -operator and NULLs

This has been been discussed before, but Oracle behaves differently, and IMHO
in a more correct way.

The following query returns NULL in PG:
SELECT NULL || 'fisk';

But in Oracle, it returns 'fisk':
SELECT NULL || 'fisk' FROM DUAL;

The latter seems more logical...
