Ah, now this is interesting. Can you please supply the definition of
the table? I'm wondering if there is a partitioned table with an FK to
this one. I'm not quite seeing how come 'tup' is NULL there. Can you
'print trigdata' in frame 2?
In general terms, this bug report would have been more actionable if you
had shown the definition of the tables involved right from the start.
