May I, as an outsider, comment? :) I really think of ASC NULLS FIRST
(and DESC NULLS LAST) as the way to go. Imagine a last_login column that
sorts users that have not logged in as the most recently logged in,
which is not very intuitive. I vote for sort_nulls_first defaulting to
false in order not to break bc.
But then, when ordering by login date, you should use COALESCE and infinity
for them
(http://www.postgresql.org/docs/8.2/interactive/datatype-datetime.html).
It's not an easy thing to do with for example Propel 1.2 ORM (written in
PHP):
$criteria->addDescendingOrderByColumn(myPeer::LAST_LOGIN); // no place
to shove database-specific attributes in.
which was my main point.
