Hello, hackers!

When debugging is enabled for server logging, isolation tests fail because there're no corresponding output functions for InsertStmt / DeleteStmt / UpdateStmt that are used in the output of the MergeAction nodes (see the attached regressions diffs and output). I also attached a try that makes the tests pass. Sorry if I missed that it was already discussed somewhere.
