Re: ERROR: could not read block 4707 of relation 1663/16384/16564: Success

My guess is some one moved the data folder or the directory got deleted (/var/lib/pgsql/9.0/data/.../...1663/16384/16564). Without server restart. I am sure some experts gonna answer this very well.

Thanks

Hi,

I am using postgresql on Glassfish server and I have EJB 3.0 for ORM. I am trying to run a query in PSQL but receiving following error:

It is kind of weird to have an error that ends with success :)

Do you have any opinion about this problem? Thanks in advance.
