Cache loolup failed problems with tsearch following pg_restore

Hi,

I'm am having real problems restoring a database which uses tsearch2.
I've followed the dump/restore notes in the tseach2 documents. After
much fiddling, I have managed to restore the database. However, as soon
as I call a SP which updates a table which uses ts_vector. I get the
following error:
2004-03-23 11:53:03 [27000] ERROR: fmgr_info: function 534990: cache
lookup failed

The following is from the pg errorlog:

PostgreSQL 7.3.3 on i386-redhat-linux-gnu, compiled by GCC 2.96

I'm totallly stuck - I have seen pg postings which refer to droping and
re-creating SPs but I don't have the knowledge of tseach2 to understand
all the dependencies.
Hope someone can help!!

Cheers

Mike
