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.

Are you overriding the default location that Debian uses?:

https://wiki.debian.org/PostgreSql

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.
