Is it possible to modify source code in executor to keep a log of old tuples and new tuples after an UPDATE, INSERT or DELETE command is executed? (so basically Store Old Tuple Values -> UPDATE/INSERT/DELETE Command -> Store New Tuple Values) For example is it possible to modify the execMain.c file in backend/executor/ such that before the ExecutorRun you save the tuples in a log file and after running ExecutorRun you log the new tuples also. How can this be achieved (if at all possible)? If it is not possible to do this by modifying execMain.c file how else can I do it? (may be nodeModifyTable.c) Please correct me if my understanding is wrong. I am new to Postgresql and to source code programming specially. I would really appreciate it a lot.
