As I understand you have compiled the binaries yourself. In that case I
think the only option is to recompile from the same sources with
different configuration (this should be fairly fast unless you removed
the object files). I don't know if there is a smooth way to use
prepackaged (in form of RPM) version of PL/Python in this case.

This is version of the PL/Python for the base system version of
PostgreSQL. This version is very old and not supported anymore by the
developers. You need to have matching version of Postgres server and
PL/Python.

Maybe others can give more insight if marrying compiled and packaged
extension can work. I'd use the packaged version of Postgres server and
PL/Python from official repository here: http://yum.postgresql.org

Hi Jwo,

I am sorry, we have built Postgresql from the Centos 7 repository. Not from the source.
Is there any option to add this Language now ? If I need to rebuild with this option, what is the procedure to do that
?

Thanks,
Srikar
