The name of the "DEBUG" severity level of PostgreSQL server events in a language used by the server.
Remarks
If PostgreSQL server returns event severity levels in other language than English, set this property to the name of the "DEBUG" severity level in a language used by the server if you want event severity to be correctly detected and assigned to the Severity or PgSqlException.Severity properties. Otherwise, these properties will be set to Severity.Unknown.
