The article on the Slony front page "Slony-I 1.1.5 release candidate 
RC3" contains a broken link to download the RC3 files - note that 
although the text for the link says "slony1-1.1.5-rc3.tar.bz2" the 
actual URL it points to is 
http://developer.postgresql.org/~wieck/slony1/download/slony1-1.1.5-rc2.tar.bz2 
(note that's -rc2 not -rc3)
