Yeah.  The release note entry is simply wrong to say it's WAL segment
size.  I would also argue that d3b111e32's installation.sgml changes
were poorly worded, because they only say "segment size" which can
easily be misunderstood, just as happened here.  Better would be
"relation segment size" or "table segment size".
