problem in database backup

Hi All,

I'm using Postgresql V7.3.3, on that i created one database with name "mydb".

 PostgreSQL 7.3.3 on i686-pc-linux-gnu, compiled by GCC gcc (GCC) 3.2 20020903 (Red Hat Linux 8.0 3.2-7)

While taking a backup of my postgresql database, i'm getting the below error.

bash-2.05b$ pg_dump mydb >mydb.out
pg_dump: server version: SAGES/pg_dump.mo; pg_dump version: 7.2.2
pg_dump: aborting because of version mismatch  (Use the -i option to proceed any
================================================================

bash-2.05b$ pg_dump -i mydb > mydb.out
pg_dump: server version: SAGES/pg_dump.mo; pg_dump version: 7.2.2
pg_dump: proceeding despite version mismatch
pg_dump: query to obtain list of data types failed: ERROR:  Attribute "typprtlen" not found
==============================================================

After getting these errors, i tried to check the version of pg_dump on my system by using the below command. Here is the result .....

[root@sql-linux root]# find / -name pg_dump -print
/root/postgresql-7.3.3/src/bin/pg_dump
/root/postgresql-7.3.3/src/bin/pg_dump/pg_dump
/usr/bin/pg_dump
/usr/local/pgsql/bin/pg_dump

============================================================

Kindly guide me to solve this problem. ..

Thanks in advance,

With Regards,

Vijay
