Unless this 8.4 install was itself upgraded from 8.3 using pg_upgrade,
you can go right from 8.4.3 to 9.0.4.

The reason for the fix in 8.4.8 was to take care of people who use(d)
pg_upgrade to upgrade from 8.3 to 8.4. Those people needed 8.4.8
released with the bug fix in order to correct the problem that could be
in their 8.4 databases. If you did an 8.3->8.4 pg_upgrade on this
system before, you might want to do the standard fix suggested using
8.4.8. But if this has always been an 8.4 system, you can just go right
to 9.0.4.
