I'm comparing now different version of page layer, and I have two questions:
1) We now store only low 16bits TLI, but name in structure stays same.
Maybe pg_tli_lo could be better.
2) HASOID has been moved in infomask and original place is unused. Is
there some reason for that? This change little bit complicate tuple
header upgrade. If there is not real reason to have it in current place,
I recommend to move it back.
thanks Zdenek
