Question

PostgreSQL

There is an entry in the table that they are trying to delete. It could be referenced from other tables, respectively, in this case, you need to display a message about the impossibility of deletion.
How to check if a post can't be deleted?
try {
$model->delete();
} catch (Exception $e) {
}
Such code catches this exception from a DB, the script falls down with an error.
How to catch an exception, or is there something like the canDelete() method in Yii2 to check if the deletion is possible?
I do not want to manually check if there are links to this record in other tables.
