1. Cache lookup failed error in tsearch2?

   What would be the cause of this error after upgrading from pgsql 7.4 to 8.1?
   
   usatest=# SELECT lexize[1] FROM lexize('en_stem', 'bacon');
   ERROR:  cache lookup failed for function 861011
   
   Does tsearch2 need to somehow be tweaked after the upgrade?

   How did you dump and reload?
   
   In 7.4 OIDs were used as column types in tsearch2.  They were changed to 
   regprocedure types.  
   
   There is a patch to apply to tsearch2 for 7.4 :
   http://www.sai.msu.su/~megera/postgres/gist/tsearch/V2/regprocedure_7.4.patch.gz
   
   You can also use the sql script I wrote to make mods to your tsearch2 tables 
   real time so a dump / reload will work :
