Undocumented PDO_PGSQL constants

[AndrolGenhald]

The documentation doesn't mention these (obtained through reflection):

    public const PGSQL_TRANSACTION_IDLE = 0;
    public const PGSQL_TRANSACTION_ACTIVE = 1;
    public const PGSQL_TRANSACTION_INTRANS = 2;
    public const PGSQL_TRANSACTION_INERROR = 3;
    public const PGSQL_TRANSACTION_UNKNOWN = 4;

I also noticed that using reflection with the PDO class with the PGSQL driver installed doesn't list the methods documented on that page. I assume this has something to do with the way the extension modifies an already existing class, is it worth opening a php-src issue or is this expected behavior?

Right; these 5 constants are available as of PHP 7.0.0 at least.

That is a known issue, since the driver specific methods are implemented via a mechanism similar to __call(). I think there is an open issue about that in the old bug tracker.

These constants were added by php/php-src@6ed1819 but they are not used for anything anymore. A better solution would be to delete them from php-src.
