This adds support for all types of triggers on a hypertable except INSERT AFTER. UPDATE and DELETE ROW triggers are automatically copied from a hypertable onto the chunks. Therefore, any trigger defined on the parent hypertable will apply to any row in any of the chunks as well. STATEMENT level triggers and iNSERT triggers need not be copied in this way.
