Regarding the statement_timestamp() ... if the entire query path is
parser -> rewriter -> planner/optimiser -> executor, what point in
that path would be considered the true start of the "statement"?  I
would assume that it's right at the beginning, when it is first handed
to the parser, but that's a very naive assumption.
