Hello,
I installed Postgres 9.2 on a new server that has Redhat Enterprise Linux 6, which came with Postgres 8.4. I did not want to use the 8.4 and never ran initdb on it. Instead, I installed postgres 9.2 via yum and di the initdb, etc, on 9.2 and have been using only that version. I have the postgres 8.4 service shut down and set to not start up upon reboot. Whenever I log into one of my databases, I always get this warning:
-bash-4.1$ psql testdb
psql (8.4.13, server 9.2.9)
WARNING: psql version 8.4, server version 9.2.
Some psql features might not work.
Type "help" for help.
testdb =#
Inside the database it says it is version 9.2:
testdb =# select version();
version
--------------------------------------------------------------------------------------------------------------
PostgreSQL 9.2.9 on x86_64-unknown-linux-gnu, compiled by gcc (GCC) 4.4.7 20120313 (Red Hat 4.4.7-4), 64-bit
(1 row)
testdb =#
And the version file of the database says it is 9.2:
-bash-4.1$ cat /var/lib/pgsql/9.2/data/PG_VERSION
9.2
-bash-4.1$
So how can my server have psql 8.4, but server 9.2? So far I have not noticed any problems with the databases and queries against them work, but could it become a problem at some time? Do I have to do something to upgrade the psql 8.4 to 9.2?
Thanks for any advice,
Julie
the psql binary you are using to connect is default binary that is 8.4. This message just means that the psql client is of an older version than the database.
To correct this you can modify the default path to point to psql binary of your newly installed postgres version. On Mon, Nov 3, 2014 at 5:32 PM, Davenport, Julie <JDavenport@xxxxxxxx> wrote:
