Thread: Parallel versions on Red Hat Linux ES v3

Parallel versions on Red Hat Linux ES v3

Hi All

I am currently running PostgreSQL v7.3.6 on Red Hat Linux ES v3 because that
is what Red Hat gave me.  Can I run PostgreSQL v7.4.6 and/or v8.0.0Beta in
parallel?

Can anyone give me some pointers on upgrading the Red Hat installation?  They
provide start up scripts and utilities that are very convenient and I do not
want to break them.  I also would like to have similar functionality on the
new installations if possible.

Red Hat says that PostgreSQL v7.4.6 will not be 'available' on Red Hat Linux
ES v3 but it will be on v4.  They aren't even talking about PostgreSQL v8.x. :-(

Kind Regards,
Keith

Yes, but not using the RPM distributions, because the different RPMs
will want to overwrite the same files (eg, /usr/bin/postgres).  You'd
need to build the non-default installations from source and specify
nonstandard install directories.
