* Guidance Needed for Testing PostgreSQL Patch (CF-5044)

Hi,
I recently installed and tested the CF-5044 patch using the query provided on the PostgreSQL community page but could not confirm its functionality. I followed the standard process:

  1.  Applied the patch using  git.
  2.  Rebuilt PostgreSQL from source (./configure, make, make install).
  3.  Tested with the suggested query after restarting PostgreSQL.

I would appreciate your guidance on verifying patch functionality and ensuring compliance with community testing standards. If there are additional steps or tools I should use, please let me know.
Thank you for your support as I represent Newt Global in contributing to the PostgreSQL community.
Best regards,
Team from Newt Global

That's welcome!


Maybe you'll find this wiki of interest:
https://wiki.postgresql.org/wiki/Reviewing_a_Patch in this page there is 
also a link to https://www.postgresql.org/docs/current/source.html
Which is a nice place to explore probably.


I hope it'll help
