Продолжайте получать эту ошибку, когда я пытаюсь извлечь все записи для сущности из базы данных.

Глядя на исходный код PostgreSQL, драйвер JDBC заявляет, что он совместим с JDBC 4.2:

https://github.com/pgjdbc/pgjdbc/blob/master/pgjdbc/src/main/java/org/postgresql/util/DriverInfo.java

Однако в нем не реализованы новые методы JDBC 4.2.В этом случае Statement.getLargeUpdateCount(): https://github.com/pgjdbc/pgjdbc/blob/master/pgjdbc/src/main/java/org/postgresql/jdbc/PgStatement.java#L997

Таким образом, EclipseLink не может заранее знать, будет ли вызов Statement.getLargeUpdateCount() работать или нет (поскольку драйвер сообщает, что он соответствует 4.2).Однако EclipseLink, вероятно, может обрабатывать исключение SQLFeatureNotSupported лучше, чем выбрасывает PgStatement.getLargeUpdateCount().Обновление вашего вопроса с помощью полной трассировки стека поможет более точно диагностировать проблему.
