That's never going to work because of quoting issues, and it wouldn't be
an efficient way if it did work (because of having to re-parse and
re-plan the INSERT each time). And if it did act the way you are
imagining, it still wouldn't be a good way because you typically want
some additional columns in the log table, such as a timestamp.

In recent releases you can do it like this:

INSERT INTO cpe_health_history VALUES (NEW.*);

which can be extended to, eg,

INSERT INTO cpe_health_history VALUES (NEW.*, now());
