Thank you Brian. But, making a database connection is very expensive if 
database connection already exists.
If you need to access database in pkt4_receive then it would be very 
expensive to use database connection for every packet received.
That is why i was asking for a mysql connection pointer few years ago:

But, i am not sure if it's implemented or not. As far as i can see it's not.
