                          When you're extending [PostgreSQL in C](https://www.postgresql.org/docs/current/xfunc-c.html) , how does one introspect/debug/dump a variable? Is there a method other than returning a custom result set to the client? Something like a printf that I can receive in a log on the server, or on the client?
