Strange behaviour with self written class

Hello,

    I've written a class for the pgsql_* function ( just a
wrapper to speed up things and have a cleaner interface, I've
attached it). While working with it, I've made some interesting
observation :

When create my first instance of the class all works ok; then,
later in a function in my new php file I create another instance
of the same class; this time the connection can be established,
but its somehow corrupted and subsequent queries fail because of
this:

called dbpg->connect()
connectstring -> host=XXXXXXXXXXXXXX user=XXXXXX password=XXXXXXX dbname=XXXXXX
connect() succeeded
connectLink = resource
resource(1) of type (pgsql link)

called        <- function called
called dbpg->connect()
connectstring -> host=XXXXXXXXXXXXXX user=XXXXXX password=XXXXXXX dbname=XXXXXX
connect() succeeded
connectLink = resource
resource(1) of type (Unknown)

its still of type resource, but its resource type is NOT pgsql
link like above but 'Unknown'.

Anyone know whats wrong or why this happening ?

thanks
    Markus
