Yes. I should have elaborated a bit more.

I think this is in reference to his earlier post mentioning a REF CURSOR from
a stored procedure. There is no support for binding a PHP var to a cursor
like the Oracle functions offer. (OCINewCursor, OCIFreeCursor)

You can always manage things directly with the query interface. I think he
wants to manage things with the PHP interface. And you can't with the
PostgreSQL functions provided. AFAIK.

That's all I was saying,
