Install postgresql-plpython for postgres 11

Hello Experts,

I wanted to install PL/Python (package name: postgresql-plpython) on Postgres 11.2 version running on AWS with Centos 7.

Is there any way  to add this language for my running postgres server ? As we have used the source package to install Postgresql 11 without giving option --with-python

I tried to find for packages in Centos 7 repo, but found this one and it needs the dependency to install  postgresql-server.

postgresql-plpython                                  x86_64                                  9.2.24-1.el7_5                                     base

Can you please advise on how to go about this ?

Regards,

Srikar
