Rebuild pg_toast from scratch? - Mailing list pgsql-general

Hi,
     I have an issue with a Windows 10 PC with Postgres 9.1 x86.
Running some SELECTs we got "ERROR: could not open file 
"base/48121/784576": No such file or directory"

I then ran

select
n.nspname AS tableschema,
     c.relname AS tablename
from pg_class c
inner join pg_namespace n on (c.relnamespace = n.oid)
where c.relfilenode = 784576;

and discovered that the involved table is pg_toast_49713.

Now I need to recreate an empty copy of this table (data can be 
recovered later), how can I achieve this?

Thanks in advance
Moreno.-
