Response body

object

allow_list

array of strings

Controls access to the Managed Database.

Individually included IP addresses or CIDR ranges can access the Managed Database while all other sources are blocked.
A standalone value of 0.0.0.0/0 allows all IP addresses access to the Managed Database.
An empty array ([]) blocks all public and private connections to the Managed Database.

allow_list

cluster_size

integer

Defaults to 1

The number of Linode instance nodes deployed to the Managed Database.

Choose 3 nodes to create a high availability cluster that consists of one primary node and two replica nodes.
A 2 node cluster is only available with a dedicated plan. It consists of one primary node and one replica node.

created

date-time

Read-only When this Managed Database was created.

encrypted

boolean

Defaults to true

Read-only Whether the Managed Databases is encrypted. Currently required to be true.

Filterable, Read-only The Managed Database engine type.

engine_config

object

Advanced parameters you can apply to a PostgreSQL Managed Database, via our partner Aiven's specification. Only include the objects for parameters you want to set in your database. Omit objects for parameters you don't want to define or change.

📘
Aiven may offer additional parameters in their specification. Currently, only those listed here are supported for use in a PostgreSQL Managed Database. You can also run the List PostgreSQL Managed Database advanced parameters operation to see an up-to-date list.

object

PostgreSQL-specific advanced configuration parameters.

pg_stat_monitor_enable

boolean

Enable the pg_stat_monitor extension. When this extension is enabled, PostgreSQL restarts the cluster it's in. Additionally, pg_stat_statements results for utility commands are unreliable.

pglookout

shared_buffers_percentage

number

20 to 60

Percentage of total RAM that the database server uses for shared memory buffers. Valid range is 20-60 (float), which corresponds to 20% - 60%. This setting adjusts the shared_buffers configuration value.

work_mem

integer

1 to 4

Sets the maximum amount of memory in MB to be used by a query operation, such as a sort or hash table, before writing to temporary disk files. Default is 1MB + 0.075% of total RAM, up to 32 MB.

📘
The secondary hostname is publicly visible and accessible.

integer

Read-only A unique ID that can be used to identify and reference the Managed Database.

label

string

length between 3 and 32

Filterable A unique, user-defined string referring to the Managed Database. This string needs to be unique per Managed Database engine type.
