No, but that too is now delivering less precision than it used to:
regression=# select 10.1/7.0;
?column?
--------------
1.4428571429
(1 row)
versus 1.44285714285714 in prior releases.

Perhaps, but I'd be satisfied if the default precision were at least
16 digits. Again, the point is not to have any apparent regression
from 7.2.
