Turning off cascading of column types

[Dana Irvin]

Is there any to turn off cascading of column  types when establishing a foreign key relationship? It usually prompts for cascading when you create the association; however, it still seems to cascade after you save. Usually cascading is a create thing; however, in PostgreSQL I have a table with a serial (kinda like a sequence) as a PK. It doesn't make sense to have a serial in another table as a FK, because the serial would just increment and not maintain PK/FK relationship.

Using EA v7.1.833.
