Re: WARNING: psql version 8.4, server version 9.2.

Thank you Rajesh for the instructions on how to set the PATH in the .bash_profile.

You are correct, the version in use is the 8.4:

# psql -V
psql (PostgreSQL) 8.4.13
contains support for command-line editing

I found the .bash_profile only under the home directory for 8.4 (/var/lib/pgsql), not for 9.2 (/var/lib/pgsql/9.2)

So I copied the /var/lib/pgsql/.bash_profile to /var/lib/pgsql/9.2/ and modified it there to include the PATH, which it did not have before:

-bash-4.1$ cat /var/lib/pgsql/9.2/.bash_profile
[ -f /etc/profile ] && source /etc/profile
PGDATA=/var/lib/pgsql/9.2/data
export PGDATA
PATH=/usr/pgsql-9.2/bin/:$PATH
export PATH
-bash-4.1$

Then I restarted the postgresql-9.2 service and then logged into one of my databases. It worked -- I no longer get the warning, and it shows that it is using 9.2 psql, not 8.4 psql:

# su - postgres

-bash-4.1$ psql testdb
psql (9.2.9)
Type "help" for help.

testdb=#

Thanks again!
Julie

I suspect there is 8.4 is installed on the server.
check psql version whether it is 9.2 or 8.4
To check psql version psql -V it will show version of psql if it is 8.4 then set .bash_profile to 9.2 binaries.
Go to home directory of postgres and edit .bash_profile
vim .bash_profile
export PATH=/path till bin/:$PATH and save the file this will help you to solve the issue.

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
