ab02d702ef08 has removed from the backend the code able to support the unloading of modules, because this has never worked. This removes the last references to _PG_fini(), that could be used as a callback for modules to manipulate the stack when unloading a library. The test module ldap_password_func had the idea to declare it, doing nothing. The function declaration in fmgr.h is gone. It was left around in 2022 to avoid breaking extension code, but at this stage there are also benefits in letting extension developers know that keeping the unloading code is pointless and this move leads to less maintenance.
