This is not a bug. There are many ways to shoot yourself in the foot; and it
is one of them...

This query will defer all of the triggers, including the cascade ones. If you
compiles with --enable-cassert you will see:
TRAP: FailedAssertion("!(afterTriggers->query_depth >= 0)", Arquivo:
"/a/pgsql/src/backend/commands/trigger.c", Linha: 3893)
Why don't you use the syntax (DEFERRABLE and INITIALLY DEFERRED)? That will do
the Right Thing (TM).
BTW, is it worth preventing such a crash putting an elog message in trigger.c?
