PDO_PGSQL DSN

    (PHP 5 >= 5.1.0, PHP 7, PECL PDO_PGSQL >= 0.1.0)

    PDO_PGSQL DSN — Connecting to PostgreSQL databases

    Description

    The PDO_PGSQL Data Source Name (DSN) is composed of the following elements, delimited by spaces or semicolons:

    DSN prefix

    The DSN prefix is pgsql:.

    host

    The hostname on which the database server resides.

    port

    The port on which the database server is running.

    dbname

    The name of the database.

    user

    The name of the user for the connection. If you specify the user name in the DSN, PDO ignores the value of the user name argument in the PDO constructor.

    password

    The password of the user for the connection. If you specify the password in the DSN, PDO ignores the value of the password argument in the PDO constructor.

    sslmode

    The SSL mode. Supported values and their meaning are listed in the » PostgreSQL Documentation.

    Note: All semicolons in the DSN string are replaced by spaces, because PostgreSQL expects this format. This implies that semicolons in any of the components (e.g. password or dbname) are not supported.
