Setting the default to WARNING is confusing and useless, because
there are no trace_recovery calls with that debug level.  IMO the
default setting should be LOG, which makes trace_recovery() a clear
no-op (rather than not clearly a no-op).  There is circumstantial
evidence in the code that this was the original intention:

int            trace_recovery_messages = LOG;

The documentation of the parameter is about as clear as mud, too.
We need to explain what it does rather than just copy-and-paste
a lot of text from log_min_messages.
