Hello,

I'm using PG 7.3.4 under RedHat 9.0 and I've started noticing the
following type of errors:

  cannot open segment 1 of relation url (target block 537329664): No
such file or directory

How can I determine what exactly is corrupt or missing and which row is
triggering this?

I have found pgfsck (http://svana.org/kleptog/pgsql/pgfsck.html), but
that gives me some funky, unrelated(?) output, like this:


-- Detected database format 7.3
-- Scanning table url
-- Indexing toast table
-- Index complete: 0 toasted tuples
-- Table url(17129): *** SERIOUS ***: No definition found for column 1

-- Table url(17129):Page 0:Tuple 1: Unknown type timestamp (1114)
-- Table url(17129):Page 0:Tuple 1: Unknown type timestamp (1114)
...
... keeps going through Pages with the same timestamp error ...
...

As far as I can tell, the above errors/warnings are not related to the
error I am getting.


I do have a dump of this DB, in case that can be used to fix the
corrupt tuple.

I dump this DB every night with:

  pg_dump -d xxx --clean --inserts --column-inserts --format=P -v


Any help would be much appreciated.

Thanks,
Otis
