Agree. I added that in v19 patch. I was having that concern in my
mind. That's the reason I wasn't capturing current_time something like
below for the same worry that current_timestamp might be the same (or
nearly the same) as the slot creation time. That's why I ended up
capturing current_timestamp in a separate query than clubbing it up
with pg_create_physical_replication_slot.
SELECT current_timestamp FROM pg_create_physical_replication_slot('foo');

LGTM. I've merged the diff into v19 patch.
Please find the attached v19 patch.
