But can anything ever see more than one version of what's in the table? Even if you rollback you should still be able to just update a row counter because nothing else would be able to see what was rolled back. Speaking of which, if a temp table is defined as ON COMMIT DROP or DELETE ROWS, there shouldn't be any need to store xmin/xmax, only cmin/cmax, correct? -- Jim C.
