Hi i have a problem using tsearch2 with postgresql. Executing:

Try the following:
SELECT oid,* FROM pg_proc WHERE proname='to_tsquery';
That should show whether there is a function with that OID.
My recollection is that older versions of tsearch2 use a configuration
table that stores function OIDs. If you dump and restore that table
verbatim then you'll get failures like this because the new installation
has different OIDs for those functions. See the tsearch2 documentation
for workarounds, but I think you're supposed to install tsearch2 before
you restore the old dump.
Yes, you:
1. Create the db
2. Install tsearch2
3. do a pg_restore -l/-L and remove the tsearch2 elements when restoring.
However, Matroska80 did say that no dump/restore had occurred. That is
right, isn't it?
