I found 3 constrains for this reference. I dropped successfully the
first. But when I tried to drop the second and the third I got the message:
"ERROR: DropTrigger: there is no trigger RI_ConstraintTrigger_494494 on
relation tperson. "

I checked the table (\d tperson) and indeed they diappeared. But I in
the table pg_trigger I still see the the other, which were refused to drop!

Any idea what went wrong?
