Upgrading PostgreSQL version

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 parameter.

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. Run 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 information about creating this file, see this guide.

   For a complete list of configurable Managed Service for PostgreSQL cluster fields, refer to the Terraform provider guides.

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

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

3. Make sure the settings are correct.

   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 updating the resources.

   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.

   Time limits

   A Terraform provider sets the timeout for Managed Service for PostgreSQL cluster operations:

   • Creating a cluster, including restoring from a backup: 30 minutes.
   • Editing a cluster: 60 minutes.
   • Deleting a cluster: 15 minutes.

   Operations exceeding the set timeout are interrupted.

   How do I change these limits?

   Add the timeouts block to the cluster description, for example:

   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 save it as an environment variable:

   export IAM_TOKEN="<IAM_token>"
   

2. Use the Cluster.Update method and send the following request, e.g., via cURL:

   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 from the folder’s cluster list.

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

1. Get an IAM token for API authentication and save it as 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 the repository contents are stored in the ~/cloudapi/ directory.

3. Use the ClusterService.Update call and send the following request, e.g., via gRPCurl:

   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 you want to update as an array of strings (paths[]).

     Here, we provide only one setting.

   • config_spec.version: New PostgreSQL version.

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

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