non-blocking CREATE INDEX in 8.2??

According to http://developer.postgresql.org/index.php/Feature_Matrix,
8.2 has non-blocking CREATE INDEX, which is news to me. Is it correct?

http://developer.postgresql.org/index.php?title=Feature_Matrix&oldid=1734
is the version where that was added (very early in the history of the
page).
