I still didn't test, but there appears to be code for relhastriggers:
void
vac_update_relstats(Relation relation,
BlockNumber num_pages, double num_tuples,
BlockNumber num_all_visible_pages,
bool hasindex, TransactionId frozenxid,
MultiXactId minmulti,
bool in_outer_xact)
{
...
if (pgcform->relhastriggers && relation->trigdesc == NULL)
{
pgcform->relhastriggers = false;
dirty = true;
}
