ingres_pconnect - Open a persistent connection to an Ingres database

SYNOPSIS
       resource ingres_pconnect ([string  $database], [string  $username], [string  $password], [array	$options])

DESCRIPTION
	Open a persistent connection to an Ingres database.

	There  are  only  two  differences between this function and ingres_connect(3): First, when connecting, the function will initially try to
       find a (persistent) link that is already opened with the same parameters. If one is found, an identifier for it will be returned instead of
       opening	a  new	connection. Second, the connection to the Ingres server will not be closed when the execution of the script ends. Instead,
       the link will remain open for future use (ingres_close(3) will not close links established by ingres_pconnect(3)). This	type  of  link	is
       therefore called "persistent".

PARAMETERS
	      o $database
		- The database name. Must follow the syntax: $[vnode::]dbname[/svr_class]

	      o $username
		- The Ingres user name

	      o $password
		- The password associated with $username

	      o $options
		- See ingres_connect(3) for the list of options that can be passed

RETURN VALUES
