Ensure 'Log_error_verbosity' Database Flag for Cloud SQL PostgreSQL Instance Is Set to 'DEFAULT' or Stricter

The 'log_error_verbosity' flag controls the verbosity/details of messages logged. Valid values are: 'terse' or 'default' or 'verbose' 'terse' excludes the logging of 'DETAIL', 'HINT', 'QUERY', and 'CONTEXT' error information. 'verbose' output includes the 'SQLSTATE' error code, source code file name, function name, and line number that generated the error. Ensure an appropriate value is set to 'default' or stricter.

CloudSql where databaseVersion like 'POSTGRES%' should have settings.databaseFlags contain [ name like 'log_error_verbosity' and value in('default','verbose')]


From Portal

  1. Go to https://console.cloud.google.com/sql/instances and navigate to the instance where the flag needs to be set
  2. Click Edit Configurations
  3. Under flags section, choose add flag, look for log_error_verbosity and choose value - 'default' or stricter.
  4. Save and review your changes

From TF
Set the flag 'log_error_verbosity' to 'default' or stricter:

resource 'google_sql_database_instance' 'default' {
	settings {
		database_flags {
			name  = 'log_error_verbosity'
			value = 'default'

From Command Line

  1. First retrieve all existing flags values:
gcloud sql instances describe INSTANCE_NAME
  1. Add all existing flags and their value to the patch request - otherwise they will get set to their default value.
gcloud sql instances patch INSTANCE_NAME --database-flags (ExistingFlag1=Value1,ExistingFlag2=Value2,...),log_error_verbosity='default'
