Well, you didn't pick the same example, because leading blanks are
significant in the char() datatype:
andrewtest=# SELECT 'a '::char='a'::char;
?column?
----------
t
(1 ligne)
But is it the case that Oracle doesn't treat that one any differently
from this:
andrewtest=# SELECT 'a'||NULL::char='a'::char;
?column?
----------
(1 ligne)
If that's the case, it's pretty odd.
