Autosuggest table name for foreign key

In the table structure view, when adding a new constraint for foreign key, Postico should be able to make an intelligent guess based on table and column name.

e.g. you're editing a table structure for the `orders` table and adding a new foreign key constraint on a column called `customer_id`. The database already has a table called `customers` or `customer` with an `id` field that matches the data type of the current column (`customer_id`). So Postico should be able to connect the dots and the pop-up/modal for adding the foreign key constraint can easily default to the "Referenced Table" being `customers`.

It's probably very easy to implement and would be a nice feature to have.

Start in Postico's table structure view and the modal for adding a foreign key constraint. Review how available tables and columns are presented, then verify that a matching singular or plural table with a compatible id field is selected as the default referenced table.
