+### Increase the Max Prepared Transactions for External Postgres Database
+
+If you are using an external Postgres server, you will need to ensure that the max prepared transactions is at least 1024. You can verify this information by opening the AWS Console and navigating to the RDS Service. Select your Postgres instance, open the Configuration tab, and click on the link to the database's parameter group. Search for the 'max_prepared_transactions' parameter.
+
+If the max prepared transactions is less than 1024, you will need to update the value. Click on the "Edit Parameters" button and change the value to 1024. Once you save your changes, you will need to wait for the database to apply the changes. This can be found back on the configuration tab. After it has been applied, you will need to reboot the database.
