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

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 ?
Thanks,
TG

Hello, first excuse my English
U cant do a backup whit a Client minor version than the server
U must have same version to do the backup, so U need upgrade your client (pg_dump 8.4.13) to at least 9.2.4

Hi
I wanted to take a backup of my database.
pg_dump throws a server mismatch version error
# cd backups
# su - postgres
-bash-4.1$ pg_dump mydb > mydbfile
pg_dump: server version: 9.2.4; pg_dump version: 8.4.13
pg_dump: aborting because of server version mismatch
This is a fresh install of postgresql on a red hat linux server that did not have any previous database installed on it . 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.
