In the query   select * from heap_page_items(get_raw_page('tablename',3220147));      t_infomask  is 10243 for all tuples
and in   select * from heap_page_items(get_raw_page('tablename',3220146)); this column is empty for all

In this one, t_infomask is 11011 for all the tuples, which is 0x2B03.
HEAP_XMAX_IS_MULTI is 0x1000.  I think you're looking at the wrong
pages, probably because of synchronized_seqscans.

I didn't look at the other pages.
