Normally, the cache lookup error means you've done something like:

create table
create view on table
drop table
re-create table (perhaps slightly different)
select * from view

since the view calls the table by oid, not by name, it can't find the 
original table it uses.

for you, it sounds like

create function
create table-that-uses-function-somehow
drop function
re-create function
insert into table

Are there triggers on your table? Or rules? (Both of these might 
refer to functions that might have been changed.) Or, perhaps you 
have constraints on your table that call a function that you've re-
created.

If you have a backup of your database (ie pg_dumpall), you can 
grep this file for 24011. This should be the original oid of the 
function that is lost.

Good luck!
