Apparently, pg-migrator (later called pg_upgrade) is available for pg

We can upgrade to new version if our previous version is running.
But In my Case I have only /opt/postgresql-8.3/data directory ( 110 Gb).

My server Crashes down and Postgres is not running.
I copied postgresql data directory to a new server and installed 
Postgresql8.3  but still it is not using the previous directory.



Thanks  regards
Adarsh Sharma
I donot want to upgrade

But isn't upgrading exactly what you're trying to do? And why do you
think you need to have the old database running to be able to upgrade?
According to the link I sent you, you don't.

 But In my Case I have only /opt/postgresql-8.3/data directory ( 110 Gb).

And PG 8.4 software, right? So you are in the middle of upgrading.

 My server Crashes down and Postgres is not running.
 I copied postgresql data directory to a new server and installed
 Postgresql8.3  but still it is not using the previous directory.

Check the logs to see why it isn't using that directory. Is it a
different directory than where your settings expect it? You can also
use the -D switch for pg_ctl and start PG manually like that.

First, be very, very careful. initdb already saved your data from 
destruction once, but you should never have allowed it anywhere near 
your live data in the first place.


Also, do not tempt fate: Make sure that your new installation is as 
close to identical to the old one as possible (architecture, 
endianness, word size). Starting PostgreSQL on an incompatible data 
directory should fail reliably, but it sounds as if you do not have 
current backups.


If your data is on some sort of shared storage, maybe you can take a 
snapshot before you do any more experiments?


Install with a different data directory (or make sure it is not 
mounted while you are installing), then reconfigure before starting 
the database.

Sorry to be rude, but you are in urgent need of a PostgreSQL DBA, (if you feel 
you somehow value your data).
Anyways, 8.3 catalog is not compatible with 8.4. You need to 
dump-upgrade-restore
if you just start 8.3 server with
/usr/local/pgsql/bin/postgres -D path_to_your_data_dir
what happens?
