Just in case where many users still want to see those log messages at LOG level,
I also created a second patch (0002) that introduces a new GUC,
trace_logical_decoding_messages, to control logging of logical
decoding debug messages (e.g., "logical decoding found consistent point").

With the default setting (DEBUG1 for now), these messages are effectively
logged at LOG level. Setting it to LOG suppresses them unless permitted
by log_min_messages.

At the moment, this parameter affects only a small set of messages
(about five). We can consider extending it to cover more logical
decoding messages later.
