Hmm, that might mean that the statement being generated inside the
trigger is incorrect in some way that isn't being reported. Can you
send a schema dump of your tables and I'll see if I can reproduce it.

BTW: The code in question is probably in src/backend/utils/ri_*.c [I
can't remember the exact ending of the filename]. It should be building
a statement and attempting to execute it using the SPI interface and
it looks like the execute is failing I'd guess by the message.
