Install postgresql-plpython for postgres 11

От

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

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
