importing a 7.2 db with contrib/tsearch to 7.3

If this is the wrong list, please redirect me to the correct one.

I have a PostgreSQL-7.2 installation with several databases in it which uses
the contrib/tsearch module.

I've done a
(on 7.2):
pg_dumpall
and
(on 7.3):
/usr/local/pgsql/bin/psql -d template1 -f prod2-pg7.2.dmp

I get a bunch of theese errors in the log-file:
---------------------------------------------------------------------------------------

---------------------------------------------------------------------------------------

The database seems to work just fine, and one of the tables which uses the
txtidx datatype looks like this in 7.2 and 7.3 respectively:
e4u=> select version();
version
----------------------------------------------------------------------------------------------------
PostgreSQL 7.2.2 on i686-pc-linux-gnu, compiled by GCC gcc (GCC) 3.2
(Mandrake Linux 9.0 3.2-1mdk)
(1 row)

e4u=> \d on_article_searchable
Table "on_article_searchable"
Column | Type | Modifiers
---------+---------+-----------
id | integer | not null
lang_id | integer | not null
content | txtidx |
Indexes: searchable_lang_idx,
t_idx
Primary key: on_article_searchable_pkey
Triggers: RI_ConstraintTrigger_18817,
RI_ConstraintTrigger_18823

------------
e4u=> select version();
version
-----------------------------------------------------------------------------------------------------
PostgreSQL 7.3rc1 on i686-pc-linux-gnu, compiled by GCC gcc (GCC) 3.2
(Mandrake Linux 9.0 3.2-1mdk)
(1 row)

e4u=> \d on_article_searchable
Table "public.on_article_searchable"
Column | Type | Modifiers
---------+---------+-----------
id | integer | not null
lang_id | integer | not null
content | txtidx |
Indexes: on_article_searchable_pkey primary key btree (id, lang_id),
searchable_lang_idx btree (lang_id)
Triggers: RI_ConstraintTrigger_41091,
RI_ConstraintTrigger_41094

Notice, the t_idx index is missing on the 7.3 table. Does that mean I have to
manually "install" tsearch on each database?

When I try to create the index t_idx on the table, the following error
occures:
e4u=> CREATE INDEX t_idx ON on_article_searchable USING gist (content);
ERROR: data type txtidx has no default operator class for access method
"gist"
You must specify an operator class for the index or define a
default operator class for the data type

Any help appreciated.
