Breaking currval()'s semantics is not an acceptable solution for this.
The best, fully backward compatible solution is for psql to issue
"SELECT last_value FROM <seq>" queries to get the values. This might
be a bit tricky to wedge into the structure of describe.c, but I don't
see any fundamental reason why it can't be done.
