Description

The PostgreSQL database instance flag 'log_min_messages' controls which message levels are written to the server log. Valid values include INFO, WARNING (default), and ERROR. If this flag is not set to the correct value, important messages useful for troubleshooting may not be logged.

How to fix?

Set the settings.database_flags.name attribute to "log_min_messages and settings.database_flags.value attribute to "info", "warning", or "error".

Example Configuration

resource "google_sql_database_instance" "default" {
  name                = "all-valid-flags-pg-instance"
  database_version    = "POSTGRES_11"
  region              = "us-east1"
  deletion_protection = false

  settings {
    tier = "db-f1-micro"

    database_flags {
      name  = "log_min_messages"
      value = "error"
    }
  }
}
