Surely this problem does not require adding any server-side code.

The existing functions like lastval, currval dont provide the current
sequence value always.
They work only if the sequence is already cached (nextval is called
atleast once for that sequence).
Changing the internals of lastval/currval will give the solution.
However, I feel that the functionality change
may affect the customers who use the current version.
Hence, I am sure that it requires the server side change. There are two
options here
1. Modifying the exisitng functions (or) 2. adding new functions
Thanks for your review
