I can't find anywhere to change a primary key constraint to "rely".
e.g Generated ddl to show: ALTER TABLE <table_name> ADD CONSTRAINT <primary_col> PRIMARY KEY (<table_name>) RELY
I presume this is only an issue if the Primary Key is in NOVALIDATE mode.
Currently Data Modeler only supports the Rely option on Foreign Key constraints.
I have logged an enhancement request to support the Rely option on Primary Key constraints.
