Hi Andrian,

The data have kept separate as in

/pgsql/data2 directory.

We are passing this path while starting the server using pg-ctl from bin directory as well this data path is given in to postgresql.conf .

So in current situation the binary is as of 9.3 and data is as of 9.2

As an alternative can we install the 9.2 and manually make the up DB is it possible Or data is lost ?. finally

If  /pgsql/data2 represents the Postgres 9.2 data directory then the data is not lost.

I am including information from your previous post in the below.

> $./initdb  -D /pgsql/9.3/main/data

Are you overriding the default location that Debian uses?:

I would look at the above to see how you can use the Debian tools to maintain/create multiple Postgres clusters.

You will need to install it again to be able to access the data in the 9.2 data directory you show above(/pgsql/data2). I would maintain that copy(/pgsql/data2) and just copy it into the 9.2 cluster when you get it reinstalled. If you want to upgrade to 9.3, then use the 9.3 pg_dumpall to dump the 9.2 data and then the 9.3 pg_restore to restore it into the 9.3 instance.

Thanks.
