Re: unexpected chunk number

Hola lista

Encontré este video para eliminar el error
https://www.youtube.com/watch?v=4jcC-lYGM0k
pero al ejecutarlo me tira un error en la sintaxis
El scrpt mencionado permite encontrar el ctid de la fila corrupta
para poder corregirlo
El codigo es el siguiente:
DO $f$
declare
curid INT := 0;
vdata BYTEA;
badid VARCHAR;
loc VARCHAR;
begin
FOR badid IN SELECT key FROM public.archivosanexos LOOP
begin
select 'ctid - '||ctid||'pagenumber - '||(ctid::text::point) [0]::bigint
into loc
from public.archivosanexos where key = badid;
SELECT contenido || ' '
INTO vdata
FROM public.archivosanexos where key = badid;
exception
when others then
raise notice 'Block/PageNumber - % ',loc;
raise notice 'Corrupted id - % ', badid;
--return;
end;
end loop;
end;
$f$;

Copio aqui la salida de consola:
comdoc=# DO $f$
comdoc$# declare
comdoc$# curid INT := 0;
comdoc$# vdata BYTEA;
comdoc$# badid VARCHAR;
comdoc$# loc VARCHAR;

Mis conocimientos son bastante limitados al respecto,
asi que agradezco cualquier ayuda al respecto.
