full text search in 8.3

Hi All,

You knew it was coming....

I have an 8.2 database that has full text searching.  I tried to 
backup/restore it to 8.3 but got lots of errors:

<snip>
ERROR:  could not access file "$libdir/tsearch2": No such file or directory
ERROR:  function public.gtsq_in(cstring) does not exist
ERROR:  could not access file "$libdir/tsearch2": No such file or directory
ERROR:  function public.gtsq_out(gtsq) does not exist
ERROR:  function gtsq_in(cstring) does not exist
<snip>
ERROR:  type "tsvector" is only a shell
ERROR:  type "public.tsdebug" does not exist
<snip>
etc...

I didn't really expect it to totally work, but I'm not sure how to move 
my db.  Any pointers would be appreciated.

I used the 8.3 pg_dump on my laptop to backup the 8.2 db from the 
server, and tried to restore on my laptop.

I tried both pg_dump -Fc, and just a pg_dump.

Am I going to need to backup the the data, and nothing else (pg_dump 
--data-only ).  Will the tsvector column be ok?

I tried doing a pg_dump --schema-only and restoring just that, but still 
got a bunch of errors (those above).  If I clean that up of all the old 
text search stuff, and then run it, then do the data, will that work ok?

One more dumb question:  I don't have to enable or install anything, do I?

Thanks,

-Andy
