PL/PGSQL

Hi pgsql list-members

I'm new at this list an want some answers for the following problem:

On every time, when my trigger is called I get
the Message:

ERROR: fmgr_info: function 87776 : cache lookup failure

What means this - or where are described ERROR-Messages at the Documentation.

What I've done:

create table test1 (x int2, free bool);
create table history (x
int2);

create function insert_history () returns opaque as
'select x into history from test1 where free=\'t\';'
language 'plpgsql';

create trigger ins1 after update on test1 for each row execute procedure
insert_history();

by and thanks
Jens
