I think you can find if there is a pg_dump through follow 2: ps -ef | grep postgres
there will be at least one line include the path of postgres server excutable file. and ls that path to show if there is a pg_dump. if your disk hasn't huge number of files, find / -name pg_dump try the result like the 9.2 one ------------------ Original ------------------ From: "Thara Vadakkeveedu";<thar...@yahoo.com>; Date: Thu, Sep 26, 2013 05:15 AM To: "alejand...@pasteleros.org.ar"<alejand...@pasteleros.org.ar>; "pgsql-admin@postgresql.org"<pgsql-admin@postgresql.org>; Subject: Re: [ADMIN] pd_dump server mismatch error Hi I did not install the client separately. I assumed i would get the right client as part of the 9.2 Yum install... I see psql is an older version too. # su - postgres -bash-4.1$ psql -d postgres psql (8.4.13, server 9.2.4) WARNING: psql version 8.4, server version 9.2. Some psql features might not work. When I installed postgresql-9.2 using Yum (yum install postgresql92 postgresql92-server) The following 3 packages were installed: postgresql92 x86_64 9.2.4-1PGDG.rhel6 pgdg92 970 k postgresql92-server x86_64 9.2.4-1PGDG.rhel6 pgdg92 3.8 M postgresql92-libs x86_64 9.2.4-1PGDG.rhel6 pgdg92 185 k I assumed this took care of installing the right client. I run the client from the same machine where the server is installed. Is there a separate package I should have installed for the 9.2 client ?

I installed postgresql 9.2 from an rpm (pgdg-redhat92-9.2-7.noarch.rpm ) using yum install. Why am I seeing this error? How can I take a backup of my database? There are two tables that have 20,000+ rows in it, that I want to backup and restore when needed. thanks thara.
