RE: Error creating plpython3u extension

Thank you Adrian and Jeff.

I made some progress and can extend databases with plpython3u.

Re. the edb doc, "C:\edb\LanguagePack-10\x64\Python-3.4\bin" does not exist, stripping 'bin' off the path is required.

Setting PYTHONHOME for the system is unfriendly to the rest of my python dependencies, so to make this specific to pg I edited the pgAdmin 4 shortcut to set the variable there, the shortcut target becomes: 

C:\Windows\System32\cmd.exe /c "SET PYTHONHOME=C:\edb\languagepack-10\x64\Python-3.4 && START  pgAdmin4.exe"

The "Start in" property does not change, the executable is found.

Whether or not this works across the server I guess I'll find out shortly, I'm a newbie doing a proof of concept so deployment isn't a concern.

Bruce

According to this:

This:

should be:

set PYTHONHOME=C:\edb\languagepack-10\x64\Python-3.4
