The problem here is that the only to option for the foreign key arrays are
NO ACTION and RESTRICT which don't allow me to update/delete a refrenced
row in the PK Table. the EXPLAIN ANALYZE only tells me that this violates
the FK constraint.
So we have two options. Either implement CASCADE or if there's a
configration for EXPLAIN to show costs even if it violates the FK

The x axis is the number if refrencing rows in the FK table
