Describe the issue Executing a query which produces integer overflow repeatedly will fail with a different exception, java.lang.ArithmeticException, after five times. The problem did not occur in driver version 42.2.11, but exist in the latest version (42.5.1).

Driver Version? 42.5.1

Java Version? 11

OS Version? Ubuntu Desktop 22.04

PostgreSQL Version? 14.5

To Reproduce

import org.junit.jupiter.api.Test;
import org.postgresql.util.PSQLException;

import java.math.BigDecimal;
import java.math.BigInteger;
import java.sql.Connection;
import java.sql.DriverManager;
import java.sql.PreparedStatement;
import java.sql.ResultSet;
import java.sql.SQLException;
import java.sql.Statement;

import static org.junit.jupiter.api.Assertions.*;

class PostgresTest {
    static final String DB_URL = ""; // TODO set DB URL here
    static final String DB_USERNAME = ""; // TODO set DB user here
    static final String DB_PASSWORD = ""; // TODO set DB password here

    @Test
    void testSelectIntegerOverflow() throws SQLException {
        try (Connection connection = DriverManager.getConnection(DB_URL, DB_USERNAME, DB_PASSWORD)) {
            try (Statement statement = connection.createStatement()) {
                statement.execute("DROP TABLE IF EXISTS IntegerOverflowTest;");
                statement.execute("CREATE TABLE IntegerOverflowTest (a BIGINT NOT NULL);");
                statement.execute("INSERT INTO IntegerOverflowTest (a) VALUES (9223372036854775807);");
                statement.execute("INSERT INTO IntegerOverflowTest (a) VALUES (1);");
            }

            for (int i = 0; i < 100; i++) {
                System.out.println("i = " + i);
                try (PreparedStatement preparedStatement = connection.prepareStatement("SELECT SUM(a) FROM IntegerOverflowTest;")) {
                    try (ResultSet resultSet = preparedStatement.executeQuery()) {
                        assertTrue(resultSet.next());
                        assertThrows(PSQLException.class, () -> resultSet.getLong(1));
                        assertFalse(resultSet.next());
                    }
                }
            }
        }
    }
}

Expected behaviour It should throw same exception each time integer overflow occurs, but it switches from org.postgresql.util.PSQLException to java.lang.ArithmeticException after five times.

Logs Did not see anything about this in the Postgres server logs.
