1. What is the meaning of those IDs in the log like "S-0xaaaae460fcb0", "C-0xaaaae45d9fb0" ? I suspect that "S-" and "C-" mean "server" and "client", but what are those HEX numbers?
These are the internal addresses of the server and client structures. You can use those to track a particular server or client connection through the logs and through SHOW SERVERS and SHOW SERVERS.
2. How would you calculate the efficiency of pgbouncer, like client_conns/server_conns ratio (current and average over over time)?
This depends heavily on what you are using pgbouncer for and what metrics are relevant for your application.
