Finally I use following formula:
#define HashMaxItemSize(page) \
MAXALIGN_DOWN(PageGetPageSize(page) - \
( SizeOfPageHeaderData + sizeof(ItemIdData) ) - \
MAXALIGN(sizeof(HashPageOpaqueData)) )
I did not replace PageGetPageSize(page), because other *MaxItemSize has
same
interface.
Revised patch is attached.
