Hi community,
I am learning the kernel of the postgres, and I want to test the make_relative_path function to know what it's operational principle.(I can read it's code, and I want to actually run it)
But I really don't know how to do it, wrtite a extension?
Can someone give me some advice?
A formal extension seems like overkill. PostgreSQL provides an ability to write customer user-space functions in C. You ought to be able to leverage that for this specific task.
