I have a problem
I have a function in plpgsql:

create function add_one (integer) returns integer as '
begin
    return $1+1;
end;
' language 'plpgsql';

When I create in psql monitor this function the message is CREATED
Then I write:
select add_one(1);
and always say:

fmgr_info: function 18816: cache lookup failed

This happend when I write any function.
How Can I resolve this problem?

I suspect you dropped the plpgsql call handler function.

If so, the only convenient recovery method AFAIK is to drop the
plpgsql language entry and all your plpgsql functions (dump them
out first!) then rerun "createlang" and reload your functions.
