PostgreSQL PDO Driver (PDO_PGSQL)

PDO_PGSQL is a driver that implements the PHP Data Objects (PDO) interface to enable access from PHP to PostgreSQL databases.

This extension defines a stream resource returned by Pdo\Pgsql::lobOpen().

Use --with-pdo-pgsql[=DIR] to install the PDO PostgreSQL extension, where the optional [=DIR] is the PostgreSQL base install directory, or the path to pg_config.

$ ./configure --with-pdo-pgsql

This extension requires libpq (the PostgreSQL C client library). As of PHP 8.4.0, libpq 10.0 or later is required.

Die folgenden Konstanten werden von diesem Treiber definiert und sind nur verfügbar, wenn die Erweiterung entweder in PHP einkompiliert oder dynamisch zur Laufzeit geladen wurde. Darüber hinaus sind diese Konstanten treiberspezifisch und sollten nur mit diesem Treiber benutzt werden. Treiberspezifische Attribute mit einem anderen Treiber zu nutzen, kann zu unerwarteten Ergebnissen führen. Wenn der Code mit verschiedenen Treibern funktioniert, kann PDO::getAttribute() verwendet werden, um mit PDO::ATTR_DRIVER_NAME den aktuellen Treiber zu ermitteln.
