Function GetCursorNumber

contrib/postgres_fdw/connection.c:655–659

* Assign a "unique" number for a cursor. * * These really only need to be unique per connection within a transaction. * For the moment we ignore the per-connection point and assign them across * all connections in the transaction, but we ask for the connection to be * supplied in case we want to refine that. * * Note that even if wraparound happens in a very long transaction, actual * coll

 * collisions are highly improbable; just be sure to use %u not %d to print.
