Installing PostgreSQL as non-root by Extracting the binaries from RPMs

[Thiagarajan Lakshminarayanan]

Hello,

In our environment, our standard RHEL OS install comes with all the
PostgreSQL required packages / libraries installed.  So, can I just extract
the binaries from PostgreSQL RPMs via rpm2cpio and create a tar file and
install it as non-root user in an alternate location?  I tested the above
approach, created a new PostgreSQL instance and it is working fine.  Please
let me know if there would be any issues with the above approach?

Thanks
Raj
