pg_task is not compatible with pg_upgrade

I tried to upgrade from PG16 with pg_task to PG18 and got an error:

Workaround: exclude pg_task from shared_preload_libraries and include after pg_upgrade

What command exactly did you use to do this?

I don't think this is such a frequent operation that I need to put a hook on every drop database to stop the extension.

In fact, it is enough to set pg_task.json = '[]' and reread the configuration to stop the extension.

I agree with you. Therefore, I suggest simply expand the README description
