Ensure server parameter 'log_checkpoints' is set to 'ON' for PostgreSQL Database Server

Explanation

Postgresql can generate logs for checkpoints to improve visibility for audit and configuration issue resolution.

Possible Impact

No error and query logs generated on checkpoint

Suggested Resolution

Enable checkpoint logging

Insecure Example

The following example will fail the azure-database-postgres-configuration-log-checkpoints check.

resource "azurerm_resource_group" "example" {
  name     = "example-resources"
  location = "West Europe"
}

resource "azurerm_postgresql_server" "example" {
  name                = "example-psqlserver"
  location            = azurerm_resource_group.example.location
  resource_group_name = azurerm_resource_group.example.name

  administrator_login          = "psqladminun"
  administrator_login_password = "H@Sh1CoR3!"

  sku_name   = "GP_Gen5_4"
  version    = "9.6"
  storage_mb = 640000
}

Secure Example

The following example will pass the azure-database-postgres-configuration-log-checkpoints check.

resource "azurerm_resource_group" "example" {
  name     = "example-resources"
  location = "West Europe"
}

resource "azurerm_postgresql_server" "example" {
  name                = "example-psqlserver"
  location            = azurerm_resource_group.example.location
  resource_group_name = azurerm_resource_group.example.name

  administrator_login          = "psqladminun"
  administrator_login_password = "H@Sh1CoR3!"

  sku_name   = "GP_Gen5_4"
  version    = "9.6"
  storage_mb = 640000
}

resource "azurerm_postgresql_configuration" "example" {
  name                = "log_checkpoints"
  resource_group_name = azurerm_resource_group.example.name
  server_name         = azurerm_postgresql_server.example.name
  value               = "on"
}
