# model_constraint Model Constraint This model tracks PostgreSQL foreign keys and constraints used by Odoo models. - Catalog: `Odoo` - Schema: `ir` The data in this table is partitioned per value of the column. This is a read-only table. The Odoo API may not support changing the data or the Invantive SQL driver for Odoo does not cover it.
