8.2.5 -> 8.3 beta tsearch2 help

["rkmr.em@xxxxxxxxx" <rkmr.em@xxxxxxxxx>]

i tried to restore a dump from 8.2.5 in which i had used tsearch2 and
contains lot of tsearch2 index. when i tried to restore it to 8.3beta
it complained about 'unknow command \r\n' . i know it is from tsearch2.
doesnt 8.3 have tsearch2 enabled by default?
with 8.2xx i used to create a database and run tsearch2.sql [from share/contrib/tsearch2 ], how do i do it in 8.3?
thanks
