Hi,
I understand this is very old topics but ...
I tried to find where such lock mark is defined in each tuple on disk, but I
failed to find such definition in include/access/htup.h. Only the bit
relevant to lock is HEAP_XMAX_UNLOGGED and I understand this bit is used only
when we have to split a big tuple into multiple blocks or to toast it.
I need to know where such "lock marks" are stored in the source level.
Any hint is appreciated.
Thanks,
