When ever I try to create extension plpython3u ERROR: could not load library "C:/Program Files/PostgreSQL/14/lib/plpython3.dll": The specified module could not be found. This message shows up I can't add extension. I am running my PostgreSQL server in windows 10

Command That I am Using 'CREATE EXTENSION plpython3u ;' OS 'Windows 10' PostgreSQL version '14' Python Version '3.11.8'

I have read all similar error and I also tried below fixes

  • Adding Environment variable for python
  • Check python version compatibility file:///C:/Program%20Files/PostgreSQL/14/doc/installation- notes.html directory

This error typically occurs due to a missing or incompatible library in the specified path. To resolve this issue and achieve seamless integration of Python with PostgreSQL using the plpython3u extension on Windows 10, you can try the following steps:

  1. Ensure Python Installation: Double-check that Python 3 is installed and properly configured on your system. Make sure it is added to the system's PATH variable.

  2. Library Path Verification: Confirm that the file "plpython3.dll" exists in the "C:/Program Files/PostgreSQL/14/lib/" directory.

  3. Check PostgreSQL Version Compatibility: Ensure that the Python version you have installed is compatible with the PostgreSQL version (14) you are using.

  4. Environment Variables: Verify that the necessary environment variables for Python and PostgreSQL are correctly set.

  5. Restart PostgreSQL Server: After making any changes, ensure to restart the PostgreSQL server to apply the modifications.

By addressing these points and verifying the configuration settings, you should be able to successfully create the plpython3u extension without encountering the specified module error.
