Hi Dan,
Seen that once before and haven't thoroughly investigated yet but I
think the new PG removal stuff just revealed this "issue". In fact it
had been in the code before the patch.
The warning means that new object(s) (given the object names these are
apparently system objects, don't remember what's this exactly) has been
written to a PG after it was staged for removal.
New PG removal properly handles that case - that was just a paranoid
check for an unexpected situation which has actually triggered. Hence
IMO no need to worry at this point but developers might want to validate
why this is happening....
Thanks,
Igor

Hi Igor,
After updating to 14.2.19 and then moving some PGs around we have a
few warnings related to the new efficient PG removal code, e.g. [1].
Is that something to worry about?
Best Regards,
Dan
