Hi,

We can try installing version 8.4.9, but when downloading the
software, we installed the binaries and files given in postgresql web
page named as version 9.1.3. This is the tar file downloaded:

postgresql-9.1.3.tar

Containing the following when un-tar-ed:

[postgsql@localhost postgresql-9.1.3]$ pwd
/postgresql/postgresql-9.1.3
[postgsql@localhost postgresql-9.1.3]$ ll
