Обсуждение: ORDER BY logic in PostgreSQL source code
I'm currently working on a GiST extension for PostgreSQL and I ran into strange ORDER BY results during my queries.
Because I can't find the problem in my source code, I want to investigate the issue by looking at the PostgreSQL source,
maybe inserting extra log messages.
While trying to do this, I came to the conclusion that I need developer help, because I can't find the part of the source code
where the ORDER BY logic is implemented.
Could you please help, by telling me which files should I take a look at?
Thanks in advance!

I think you can start by looking into the function grouping_planner and explore further by going through the route of it. -- Regards, Rafia Sabih
