So you are using the deb packages. The above is for the Postgres 9.3 cluster, where is the data from the Postgres 9.2 cluster?
The person was doing the activity did not check the varsion.
What do you mean by setting of replication?
Enabling the Archive and WAL setting.
So was this done before the upgrade, during, after? I am just not seeing the connection to the error you reported.
----It was done before upgrade.
Now when initializaing the DB getting the error as below.
So you ran initdb to create a cluster >
Yes ..
What was the exact command you used.
----Calling bin $./initdb -D /pgsql/9.3/main/data
The database cluster was initialized with PG_CONTROL_VERSION 922, but the server was compiled with PG_CONTROL_VERSION 937.
The above would seem to indicate you tried to start a Postgres 9.3 server using a Postgres 9.2 data directory.
Yes.it seems right.
That is not possible as you found out. When doing an upgrade between major versions(see note below) in Postgres you either have to dump the data from the older version and restore it to the new version or you need to use pg_upgrade.
*NOTE* Up to Postgres version 9.6.x a major version change was a change in either of the first two numbers. Starting with the next release (10.x) only the first number is a major version.
At this point you should have two Postgres clusters on you machine, Something like:
/var/lib/postgresql/9.2/main/
/var/lib/postgresql/9.3/main/
Is this correct?
Only /var/lib/Postgresql/9.3/main
9.2 is uninstalled now.
Currently we have only 9.3 version.
Any solution if DB can be upgraded from 9.2 to 9.3.
You are trying to upgrade from Postgres 9.2 to 9.3?
