I dunno if it was "rare" or not --- basically, anytime you did a
multicolumn sort where some tuples match up to and including a
NULL column, you'd find that the columns to the right of the NULL
weren't sorted.  Maybe instead write

* Fix for sorting of NULLs in multicolumn sorts

A couple other things to add:

* Shared library dependencies fixed (this time for sure ;-))
* Fixed glitches affecting GROUP BY in subselects
        regards, tom lane

Done.
