Re: postgresql14-contrib does not install with libpython 3.7

Hi Marcia,

Thanks again, worked perfectly!

In my case, I'm using 14.8, so I used that version and compiled against python 3.7 with no issues. The last part was manual as I copied the generated pg contrib files from [/usr/pgcontrib_py/pgsql-14/ ] to those same folders in [/usr/pgsql-14/] as those folders existed already and had files in them, only one folder had the same two files***, so I excluded them from overwriting since they were the same size.

Thanks again, really appreciated!

Alex

​***[root]# cp /usr/pgcontrib_py/pgsql-14/lib/* /usr/pgsql-14/lib

- cp: overwrite ‘/usr/pgsql-14/lib/dict_int.so’? ncp: overwrite ‘/usr/pgsql-14/lib/dict_xsyn.so’? n

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?
