PostgreSQL FAQ
As for now, DBaaS is only offered on Virtual Servers. Cloud Cubes may be used in the future as well.
IONOS DBaaS doesn't provide connection pooling. However, you may use a connection pooler (such as
pgbouncer) between your application and the database.Depending on the library you are using, it should be something like:
failed to create DB connection: addr x.x.x.x:5432: connection refused.The best way to manage connections is to have your application maintain a pool of at least 10-20 connections. It is considered bad practice to have a lot of DB connections. However, letting the user configure
max_connections themselves in the future is an option.We provide an automated backup within our cloud. If you want to backup to somewhere else, you may use a client-side tool, such as
pg_dump.The number of standby nodes (in addition to the master) doesn’t really matter. If you have one or ten makes no difference. Synchronous modes are slower in write performance due to the increase in latency for communication between master and standby.
If you're receiving an error message
Parameter out of bounds: The recovery target time is before the newest basebackup., please check the earliestRecoveryTargetTime of your backup. Your target time of the restore needs to be after this timestamp. Maybe you have another backup for your cluster with an earlier earliestRecoveryTargetTime and can use that.If the
earliestRecoveryTargetTime is missing in your backup, the cluster from where you want to restore wasn't able to do a base backup. This can happen, when you e.g. quickly delete a newly created cluster, since the base backup will be triggered up to a minute after the cluster is available.Last modified 3mo ago
