Detailed Description​

A scan of a table by TupleID - known as TID or CTID. This will give very fast access to specified rows, as the TID is an actual address on disc. However, TIDs cannot be relied on long term as a row’s TID can change through vacuum operations or re-organisation activities. TID is similar in use to an Oracle RowID.
