Re: postgresql14-contrib does not install with libpython 3.7

Hi Marcia,

Thank you so much! I'll try that and will let you know how it goes. 

Thanks again, I really appreciate it.

Hi, Alex

This is what I did using Daniel suggestions:

[root]# yum groupinstall "Development tools" [root]# useradd postgres [root]# yum install readline-devel [root]# yum install zlib-devel [postgres]$ wget https://ftp.postgresql.org/pub/source/v14.2/postgresql-14.2.tar.bz2 [postgres]$ tar -xvf postgresql-14.2.tar.bz2 [root]# mkdir /usr/pgcontrib_py/pgsql-14 [root]# cd postgresql-14.2/ [root]# PYTHON=/bin/python3 [root]# ./configure --prefix=/usr/pgcontrib_py/pgsql-14 --with-python [root]# cd contrib [root]# gmake clean [root]# gmake [root]# gmake install After this, the content at /usr/pgcontrib_py/pgsql-14 could be compressed and could be uncompressed under a PG 14 installation at /usr/pgsql-14/ Best regards Marcia

Hi Tom/Maria,

I'm in a similar situation using a Amazon Linux 2 server instance and by default it comes with Python 3.7. I uninstalled Python 3.7 and installed Python 3.6 and the postgres contrib-14 package installed without issue.

Of course, there was a recent security patch where we now need to remove Python 3.6 and use Python 3.7 to apply the vulnerability update.

Trying it again, with Python 3.7, I get:
Error: Package: postgresql14-contrib-14.9-2PGDG.rhel7.x86_64 (pgdg14)
Requires: libpython3.6m.so.1.0()(64bit)
Available: python3-libs-3.6.2-3.amzn2.0.2.x86_64 (amzn2extra-python3)

Can you please let me know what you did to get it work with Python 3.7. I assumed there was a source postgres-contrib14 location I could wget and build against Python 3.7 but I can't find it, so I assume someone is manually adding various extensions to this and creating packages, but offering no source to build with?

Thanks in advance for your help,

Alex
