We abandoned maintenance of the 7.1 branch in 2001. 7.2 was the first
version that anyone thought was good enough to maintain over the long
haul (mainly because it was the first version that wouldn't crash and
burn at 4G transactions), and even that was abandoned in 2005 because
of its unfixable-without-initdb security bugs.
I don't know of anyone who would recommend today that you undertake new
development on a server version older than 8.1.x.
