Re: [ADMIN] ERROR: could not read block

[Apologies for the delayed response; fighting through a backlog.]

I checked with out DBAs, and they are willing to test it.

By they way, they found that they were getting this on a pg_dump,
too. We will test both failure cases. If the test goes OK, we would
be happy to leave it in production with this patch.

[with reply to all followup threads] Yeah, this is the key and we
definitely
have no 100% guarantee that several retries will solve the problem -
just as
the situation in pg_unlink/pg_rename. But shall we do something now? If
Kevin could help on testing(you may have to revert the registry changes
:-()
, I would like to send a patch in the retry style.
