Did you use the source version of 9.0 and do configure/make to install it? If
so you might want to take a look at:
http://www.postgresql.org/docs/9.0/interactive/install-upgrading.html
Going from a major versions (8.1 to 9.0 in this case) requires some additional
steps. Besides the above problem you ran into, there will probably others even
if you follow the upgrade procedure. There have been a lot of changes from 8.1
to 9.0, not the least of which is the dropping of implied type casts in 8.3.
You probably want to spend some time with the Release Notes:
