Exceptions regarding existing active transactions were thrown while I was almost certain sufficient checks were in place.
However, I quickly found out that a strict boolean comparison to PDO::inTransaction() was failing.
Using var_dump I learned that this function was returning integers, not boolean values.
var_dump(PDO::inTransaction()); // int(1) || int(0)
PDO::inTransaction
(PHP 5 >= 5.3.3, Bundled pdo_pgsql, PHP 7, PHP 8)
PDO::inTransaction — トランザクション内かどうかを調べる
説明
public PDO::inTransaction(): bool
ドライバ内で、現在トランザクションがアクティブになっているかどうかを調べます。 このメソッドが機能するのは、トランザクションをサポートしているデータベースドライバのみです。
パラメータ
この関数にはパラメータはありません。
返り値
トランザクションが現在アクティブな場合に true、
そうでないときに false を返します。

On OS X 10.9 with PHP 5.4.10, this function seems to correctly return bool(true) or bool(false) and not anymore integers.

Important note: This will only detect whether a transaction has been started using beginTransaction(). It will not be able to detect transactions started by any other means, for example by executing "START TRANSACTION".

In addition to what jlh says,
even with SQLite3 which automatically starts transaction,
inTransaction() only works after beginTransaction().
<?php
try{
$pdo = new PDO('sqlite:test.sql3', null, null, [PDO::ATTR_ERRMODE => PDO::ERRMODE_EXCEPTION]);
var_dump($pdo->inTransaction());echo "<br>"; // bool(false) : before beginTransaction()
$pdo->beginTransaction();
var_dump($pdo->inTransaction());echo "<br>"; // bool(true) : after beginTransaction()
$pdo->rollBack();
var_dump($pdo->inTransaction());echo "<br>"; // bool(false) : after commit() or rollBack()
}catch (PDOException $e){
echo 'PDOException: ' . $e->getMessage();
}catch (Exception | ErrorException $e){
var_dump($e);
}

This method actually seems to work fine on PHP5.3.5 (and probably a few older versions).
