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 0: Unknown type timestamp (1114)
-- 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

If this is coming from an indexscan query, then I'd bet on the problem
being a corrupted index on the "url" table. REINDEX may get you out of
it. If not, try dumping and reloading that table (or the whole database
if need be).
7.3.4 is a bit old --- you should at least move up to 7.3.8, if not
7.4.something.

Thanks, I'll try REINDEX shortly. Before I do that, though, I'm
wondering if it's somehow possible to get the details of this problem -
I'd love to see which DB file PG is actually looking for.

Thanks for the info - I'll upgrade to 7.3.8 then, too.
