plpython3 package installation problem

[Yi Sun <yinan81@xxxxxxxxx>]

Hello,

As we need to use the plpython3u extension, we tried to install the plpython3 package but showed that we needed to install python3-libs, but python36-libs was already installed for patroni usage.

1. Will installing python3-libs affect current python36-libs usage? 

2. If we can do some configuration to let python36-libs work as python3-libs then no need to install   python3-libs? Thanks

# yum localinstall /tmp/postgresql11-plpython3-11.11-1PGDG.rhel7.x86_64.rpm
...
           Requires: python3-libs
 You could try using --skip-broken to work around the problem
 You could try running: rpm -Va --nofiles --nodigest

# yum search python3 | grep libs
python34-libs.x86_64 : Python 3 runtime libraries
python36-libs.x86_64 : Python runtime libraries
shiboken-python36-libs.x86_64 : CPython bindings generator for C++ libraries -
# yum list python36-libs.x86_64

Thank you
