Sorry, the form on the website doesn't allow selecting the master branch, so I have to choose the latest available version instead. But yes, you're right — pg_plan_advice is only available on the master branch.

Could this be related to GCC? I'm using GCC 16.1.1 and I can reproduce the crash with that version.
