Vladimir, Anton, I've been reviewing the docs of WAL on/off capabilities [1] added to 2.4 and personally think that LOGGING/NOLOGGING is not the best name to turn WAL on/off with ALTER TABLE [2].
May I suggest to name it in a more human-friendly fashion such as: ALTER TABLE table *[WAL_ON|WAL_OFF]* Hope you can do the renaming while 2.4 is still being tested and benchmarked. Sorry for late notice, but I missed the general review of the API.
