Result does not implement ResultInterface::getQueryResult() — fatal against current php-db/phpdb 0.6.x-dev #12

Summary

Pgsql\Result no longer satisfies PhpDb\Adapter\Driver\ResultInterface. php-db/phpdb#172 added getQueryResult() to the interface (commit 6a14886), and this package does not implement it, so loading the class is a fatal:

Fatal error: Class PhpDb\Pgsql\Result contains 1 abstract method and must therefore be
declared abstract or implement the remaining methods
(PhpDb\Adapter\Driver\ResultInterface::getQueryResult) in src/Result.php on line 17

This happens before any test runs, so composer update followed by composer test fails outright.

The added signature is:

public function getQueryResult(?ResultSetInterface $resultPrototype = null): ResultSetInterface;

It replaces the clone/initialize logic that previously lived in Adapter.

Proposed change

Implement the method on Pgsql\Result, following Adapter\Driver\Pdo\Result upstream:

#[Override]
public function getQueryResult(?ResultSetInterface $resultPrototype = null): ResultSetInterface
{
    if (! $this->isQueryResult()) {
        throw new Exception\RuntimeException(
            'Cannot produce a query result set from a result that is not a query result;'
                . ' check isQueryResult() first',
        );
    }

    $resultPrototype ??= new ResultSet();
    $resultSet       = clone $resultPrototype;
    $resultSet->initialize($this);

    return $resultSet;
}

isQueryResult() already exists here as pg_num_fields($this->resource) > 0, so the guard works as-is. Needs coverage for both branches.

Notes

#11 pins composer.lock to the older php-db/phpdb reference (81844a5) to avoid the fatal, which is a stopgap: the latest legs of the new matrix resolve 0.6.x-dev fresh and will fail, and the lock cannot move forward until this is fixed.

phpdb-mysql has no getQueryResult() either and its lock is pinned to an older reference again (e037464), so the same break is likely waiting there.
