Problem with restoring dump (may be tsearch-related)

Hi!

I dump all of my databases daily using pgdumpall (./pg_dumpall >
/var/pgbackup/alldb1.sql). Now if I try to restore the whole lot via
"psql -d template1 -f alldb1.sql", I get loads and loads of parse errors
like

psql:alldb1.sql:1122826: ERROR: parser: parse error at or near "ußerst"
psql:alldb1.sql:1122826: ERROR: parser: parse error at or near "chst"

psql:alldb1.sql:1122831: ERROR: parser: parse error at or near
"berzeugen"
...

I tried to restore on an freshly installed system; I compiled and
installed tsearch from contrib (just make install, I didn't prepare
template1 with it), as I use it in some tables in several databases on
the original installation. As the parse errors state substrings, I think
it might have to do something with the txtidx type not being present at
the time the inserts are being made. I can however create a sort of copy
from the original system by creating the databases on the target-server
first, then creating the tsearch-datatypes, functions and operators via
the tsearch.sql for every one of them and then finally just piping the
dump from one server to the other:

./pgsql/bin/pg_dump -h originalhost databasename | /./pgsql/bin/psql -h
targethost databasename

Now this doesn't help me much in case of a real crash when I would have
to recreate the databases from the "alldb1.sql"-dump. How can I
accomplish this? One way might be to create the databases, install
tsearch for all of them, then parse the alldb1.sql and eliminate all
"create database"-statements and the statements that are related to
installation of tsearch - but I think that this would be a bit messy and
I don't know if this method would yield guaranteed success as I don't
exactly know what exactly I would need to throw out of the alldb1.sql.
Is there some better way for restoring the dumps? Or am I doing
something wrong (most probably :) ).

Thanks for your help!
