Yes sorry, pg10 is beta - avoid using it except for testing purposes.

Note: the trigger function can either be a static function updated monthly (to
handle the next month), preferably with the most recent months tested first (so
a typical newly-inserted rows only goes through one if/case test).
Alternately, the trigger function can dynamically compute the table into which
to insert using plpgsql "format()" similar to here:
