do i need to change the jar in case of new PostgreSQL installation

["surabhi.ahuja" <surabhi(dot)ahuja(at)iiitb(dot)ac(dot)in>]

 I have been using Postgres 8.0.0 on my mc

for which i used the following jar:

 postgresql-8.0-310.jdbc3.jar

 

now i will be going for Postgres8.1.5 , 64 bit server

 

Is it ok if I countinue using the same jar?

Why i am asking is this: I have noticed a decrease in the databasae operations like delete.

Please help me in this regards

 

 

thanks,

surabhi
