PostgreSQL version upgrade

If you do not have the Yandex Cloud CLI installed yet, install and initialize it.

By default, the CLI uses the folder specified when creating the profile. To change the default folder, use the yc config set folder-id <folder_ID> command. You can also set a different folder for any specific command using the --folder-name or --folder-id options.

To upgrade a cluster to PostgreSQL version 15 or lower:

1. Get a list of your PostgreSQL clusters using this command:

   yc managed-postgresql cluster list
   

2. Get the target cluster details and check its PostgreSQL version in the config.version setting:

   yc managed-postgresql cluster get <cluster_name_or_ID>
   

3. Start the PostgreSQL upgrade:

   yc managed-postgresql cluster update <cluster_name_or_ID> \
      --postgresql-version <new_version_number>
   

1. Open the current Terraform configuration file describing your infrastructure.

   For more on how to create this file, see Creating a cluster.

   For a complete list of configurable Managed Service for PostgreSQL cluster fields, see this Terraform provider guide.

2. Add the version field to the cluster_config section of the target Managed Service for PostgreSQL cluster, or update its value if it already exists:

   resource "yandex_mdb_postgresql_cluster" "<cluster_name>" {
     ...
     cluster_config {
       version = "<PostgreSQL_version>"
     }
   }
   

3. Validate your configuration.

   1. In the command line, navigate to the directory that contains the current Terraform configuration files defining the infrastructure.

   2. Run this command:

      terraform validate
      

      Terraform will show any errors found in your configuration files.

4. Confirm resource changes.

   1. Run this command to view the planned changes:

      terraform plan
      

      If you described the configuration correctly, the terminal will display a list of the resources to update and their parameters. This is a verification step that does not apply changes to your resources.

   2. If everything looks correct, apply the changes:

      1. Run this command:

         terraform apply
         

      2. Confirm updating the resources.

      3. Wait for the operation to complete.

   Timeouts

   The Terraform provider sets the following timeouts for Managed Service for PostgreSQL cluster operations:

   • Creating a cluster, including restoration from a backup: 30 minutes.
   • Updating a cluster: 60 minutes.
   • Deleting a cluster: 15 minutes.

   Operations exceeding the timeout are aborted.

   How can I change these timeouts?

   Add a timeouts section to the cluster description, e.g.:

   resource "yandex_mdb_postgresql_cluster" "<cluster_name>" {
     ...
     timeouts {
       create = "1h30m" # 1 hour 30 minutes
       update = "2h"    # 2 hours
       delete = "30m"   # 30 minutes
     }
   }
   

1. Get an IAM token for API authentication and put it into an environment variable:

   export IAM_TOKEN="<IAM_token>"
   

2. Call the Cluster.Update method, e.g., via the following cURL request:

   Warning

   The API method will assign default values to all the parameters of the object you are modifying unless you explicitly provide them in your request. To avoid this, list the settings you want to change in the updateMask parameter as a single comma-separated string.

   curl \
     --request PATCH \
     --header "Authorization: Bearer $IAM_TOKEN" \
     --header "Content-Type: application/json" \
     --url 'https://mdb.api.cloud.yandex.net/managed-postgresql/v1/clusters/<cluster_ID>' \
     --data '{
               "updateMask": "configSpec.version",
               "configSpec": {
                 "version": "<PostgreSQL_version>"
               }
             }'
   

   Where:

   • updateMask: Comma-separated list of settings you want to update.

     Here, we provide only one setting.

   • configSpec.version: New PostgreSQL version.

   You can get the cluster ID with the list of clusters in the folder.

3. Check the server response to make sure your request was successful.

1. Get an IAM token for API authentication and put it into an environment variable:

   export IAM_TOKEN="<IAM_token>"
   

2. Clone the cloudapi repository:

   cd ~/ && git clone --depth=1 https://github.com/yandex-cloud/cloudapi
   

   Below, we assume that the repository contents reside in the ~/cloudapi/ directory.

3. Call the ClusterService.Update method, e.g., via the following gRPCurl request:

   Warning

   The API method will assign default values to all the parameters of the object you are modifying unless you explicitly provide them in your request. To avoid this, list the settings you want to change in the update_mask parameter as an array of paths[] strings.

   Format for listing settings

   "update_mask": {
       "paths": [
           "<setting_1>",
           "<setting_2>",
           ...
           "<setting_N>"
       ]
   }
   

   grpcurl \
     -format json \
     -import-path ~/cloudapi/ \
     -import-path ~/cloudapi/third_party/googleapis/ \
     -proto ~/cloudapi/yandex/cloud/mdb/postgresql/v1/cluster_service.proto \
     -rpc-header "Authorization: Bearer $IAM_TOKEN" \
     -d '{
           "cluster_id": "<cluster_ID>",
           "update_mask": {
             "paths": [
               "config_spec.version"
             ]
           },
           "config_spec": {
             "version": "<PostgreSQL_version>"
           }
         }' \
     mdb.api.cloud.yandex.net:443 \
     yandex.cloud.mdb.postgresql.v1.ClusterService.Update
   

   Where:

   • update_mask: List of settings to update as an array of strings (paths[]).

     Here, we provide only one setting.

   • config_spec.version: New PostgreSQL version.

   You can get the cluster ID with the list of clusters in the folder.
