Okay, Patch in general looks fine to me. One cosmetic comments, IMHO
in PG we follow operator at end of the line, so move '&&' to end of
the previous line.

+ if (cstate->rel->rd_rel->relkind != RELKIND_RELATION
+ && (!cstate->rel->trigdesc ||
+ !cstate->rel->trigdesc->trig_insert_instead_row))

Meanwhile I will test it and give the feedback.
