Thread: difference in MVCC in 8.3 vs 8.2

difference in MVCC in 8.3 vs 8.2

From

Hi,
 
Are there any significant changes to the MVCC concept in 8.3 vs 8.2 in terms of theory and implementation.
Is there any reason why the function must have got renamed from HeapTupleSatisfiesSnapshot to HeapTupleSatisfiesMVCC.
 
I have understood the usage of HeapTupleSetHintBits though.

Thanks,
Kenneth

The old name was misleading, because all those functions work with
"snapshots" in the sense of "values of type Snapshot".  See
