Description

The PostgreSQL database instance flag 'log_connections' causes successful and unsuccessful connections to be logged. This data can be used to identify, troubleshoot, and repair configuration errors and denial of service attacks. This flag and the 'log_disconnections' flag are typically used together.

How to fix?

Set settings.database_flags.name attribute to "log_connections", and settings.database_flags.value attribute to "on".

Example Configuration

resource "google_sql_database_instance" "allowed" {
  name             = "master-instance"
  database_version = "POSTGRES_11"
  region           = "us-central1"

  settings {
    tier = "db-f1-micro"
    database_flags {
      name  = "log_connections"
      value = "on"
    }
  }
}
