Unhandled rejection error on knex.batchInsert with postgres

[jehy]

Doing

 knex.batchInsert('keys', rows, rows.length);

when having duplicate key causes unhandled rejection error - can not catch it as a promise or with try\catch:

Unhandled rejection error: insert into "keys" ("count", "created_at", "is_active", "key", "rsa_key_id", "updated_at") values ($1, $2, $3, $4, $5, $6), ($7, $8, $9, $10, $11, $12), ($13, $14, $15, $16, $17, $18), ($19, $20, $21, $22, $23, $24), ($25, $26, $27, $28, $29, $30), ($31, $32, $33, $34, $35, $36), ($37, $38, $39, $40, $41, $42), ($43, $44, $45, $46, $47, $48), ($49, $50, $51, $52, $53, $54), ($55, $56, $57, $58, $59, $60) - duplicate key value violates unique constraint "keys_rsa_key_id_unique"

Steps to reproduce - try catching error when inserting bulk values with duplicated keys:

knex.schema.createTable('test', function (table) {
      table.string('col');
      table.unique('col');
    }).then(function () {
      var rows = [{'col': 'a'}, {'col': "a"}];
      return knex.batchInsert('test', rows, rows.length);
    }).catch(function () {
      console.log('not coming here');
    });
