По какой-то причине драйвер JDBC PostgreSQL добавляет: RETURNING * в конец операторов выбора. Зачем?
Код:
protected static final String AUTH_QUERY = "SELECT \"SECRET\" FROM \"user\" WHERE \"NAME\" = :name";
String password = sql2o.open().createQuery(AUTH_QUERY).addParameter("name", username).executeScalar(String.class);
Исключение:
org.postgresql.util.PSQLException: ERROR: syntax error at or near "RETURNING"
