Mitesh,

Your server is newer than your pg_dump program. pg_dump must be the same
version as server version. You need to upgrade your pg_dump to be
version 9.1.2. It should have installed that version when you
installed/upgraded your Postgres version but may have been installed in
a different location or the one you are using for your script is not the
one that came with your server (separate install). So all you need to do
in your script is to point to the one that comes with the server and it
will work or update the one that you are currently using in the script
to version 9.1.2.

This is not a bug. Use a version of pg_dump which is at least as
new as the server. The older version of pg_dump is unlikely to be
able to recognize everything in the newer server,

-Kevin

There used to be a switch in pg_dump that would disable the version, you can
even see that's in the man page. However, it is not reccommended and the most
recent versions have fully deprecated the switch. Technically speaking that
means that you can even use an older version of pg_dump and it wouldn't
generate any errors although I wouldn't want to test it out on important stuff.

Hi, Mitesh,

The error means exactly what it says: You're trying to use the 9.0.5 version of pg_dump to dump a server running 9.1.2; you need a version of pg_dump that is no older than the server you are trying to do the dump from.

The problem is you are using an older version of pg_dump to dump a newer
database. That will not work.
Possible solution:
You are running via cron. Cron has its own environment. Unless you are
explicit in your pathing you can get surprising results, see above.
Find the path to the 9.1.2 version of pg_dump and use that absolute path
in your script.
