I believe the OP is disabling all triggers including system ones if I 
follow correctly and possibly running a foul of;

https://www.postgresql.org/docs/current/sql-altertable.html

" Disabling or enabling internally generated constraint triggers 
requires superuser privileges; it should be done with caution since of 
course the integrity of the constraint cannot be guaranteed if the 
triggers are not executed."
