Re: [GENERAL] Tsearch2 cache lookup problem
I made a restore from a database without tsearch2 installed, installed tsearch2 executing tsearch2.sql and than used it successfully. One day after this i obtained that error as if a database corruption occurred...however noone has touched the database...

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?

But it's strange this happens now but not before and nothing has done on
database...some data break with tsearch2?
I am using postgres 7.4.6 and no dump restore occurs before this error
appear.
Either you have database corruption or something has clobbered your
function definition.
Oh, and upgrade to the latest 7.4.x series too - lots of bug-fixes
you'll want to get.

(adding to my previous reply)
Or it could be a problem with that OID. Also try:
SELECT oid,* FROM pg_proc WHERE oid=14152;
