PostgreSQL PDO Driver (PDO_PGSQL)

Introduction

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

Resource Types

This extension defines a stream resource returned by PDO::pgsqlLOBOpen().

Installation

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

Predefined Constants

The constants below are defined by this driver, and will only be available when the extension has been either compiled into PHP or dynamically loaded at runtime. In addition, these driver-specific constants should only be used if you are using this driver. Using driver-specific attributes with another driver may result in unexpected behaviour. PDO::getAttribute() may be used to obtain the PDO::ATTR_DRIVER_NAME attribute to check the driver, if your code can run against multiple drivers.

PDO::PGSQL_ATTR_DISABLE_PREPARES (int)
Alias of Pdo\Pgsql::ATTR_DISABLE_PREPARES.

General notes

Note:

bytea fields are returned as streams.
