Mediawiki 1.10 and PG 8.3 upgrade

Hello all,

I'm sure I did something wrong during my upgrade of mediawiki from
Postgresql 8.2 to 8.3. Any help on how to recover would be appreciated.

Possible useful info:
OS: Fedora 9
Postgresql: PostgreSQL 8.3.1 on x86_64-redhat-linux-gnu
Mediaiwiki: mediawiki-1.10.4-39.fc9.x86_64

My mediawiki pages are loading, but when I try to edit them, I get this
error message:

A database error has occurred Query: INSERT INTO pagecontent
(old_id,old_text,old_flags) VALUES [snip] ERROR: text search
configuration "default" does not exist CONTEXT: PL/pgSQL function
"ts2_page_text" line 3 at assignment

Backtrace:

I would like to say thanks to the people that put in so much time and
effort in developing tsearch2 (and postgresql too), your work is greatly
appreciated. However, I have never had a recent postgresql upgrade work
seemlessly, and it is almost always due to issues with tsearch2. :(

While searching the internet for magic recipes on how to perform these
upgrades that involve tsearch2, I find long complex instruction sets
detailing brain-numbingly complex operations (hand edit the schema!):

Also, I have found this blog entry from Greg Mullane which makes it all
seem so simple: (Note Tom Lane's comment, which seems to directly relate
to the error message I am seeing).

These are just a 2 examples, there are others. The one common thread
shared by all the instructions are that they say different things. How
are we, Joe PostgreSQL users on the street, supposed to know which
instructions to follow? Have I (very possible) missed some official
PostgreSQL instructions? How do we go about triaging tsearch2 problems?
