You've disabled statement logging altogether.  The zero value you were directed to use is what causes everything to be logged.

Actually no:

https://www.postgresql.org/docs/10/static/runtime-config-logging.html#RUNTIME-CONFIG-LOGGING-WHEN

log_min_duration_statement (integer)

"... Setting this to zero prints all statement durations. Minus-one (the default) disables logging statement durations. ..."

"

So -1 only affects logging statements relative to duration.

If you have log_statements set then you will still get statements logged if you have log_min_duration_statement = -1 :

Note

When using this option together with log_statement, the text of statements that are logged because of log_statement will not be repeated in the duration log message.

This is how I have my logging setup, log_min_duration_statement = -1
and log_statements = 'mod' and I see statements in the logs.
