The following is just FYI.
I was recently doing some stuff with greatest() on oracle (9.2.0.8.0) and
noticed that it returned null if ANY of the arguments were null. Out of
curiosity I checked postgres' definition of that function and found that it
returns null only if ALL of the arguments are null.
W/o knowing the SQL standard (just from what I'd perceive
as sensible) I'd say Oracle is broken. :}

choose an index scan if your joining column's datatypes do not
match
