Disable logging of logical replication statements in Postgres 13.1

Question

I have a simple process that is reading logical replication messages from postgres. This process runs every second and generates a lot of messages in the postgres logs like:

2021-02-15 20:35:11.032 UTC [35] STATEMENT:  SELECT * FROM pg_logical_slot_get_changes('lazy_cloud', NULL, NULL);
2021-02-15 20:35:11.032 UTC [35] LOG:  logical decoding found consistent point at 0/167C618
2021-02-15 20:35:11.032 UTC [35] DETAIL:  There are no running transactions.

I've configured logging with the following settings:

log_min_messages=ERROR
log_statement=none
log_replication_commands=0

But, the logical replication logs are still produced.

Is there a setting to disable these messages? I can use sed or something like that, but would prefer a built in solution.

Answer 1

There is no way to disable that message short of setting

log_min_messages = fatal

in postgresql.conf, but that is not a smart idea, because then you'd miss out on all error messages in the log file and essentially disable logging.
