That's because log_rotation_age expects the setting value in minutes.
This is not a problem only for log_rotation_age. When setting the parameter
which expects the value in seconds to less than one second, the setting value
is implicitly reset to the default. For example,
postgres=# SHOW tcp_keepalives_idle ;
tcp_keepalives_idle
---------------------
7200
(1 row)
postgres=# SET tcp_keepalives_idle TO '10ms';
SET
postgres=# SHOW tcp_keepalives_idle ;
tcp_keepalives_idle
---------------------
7200
(1 row)
postgres=# SET tcp_keepalives_idle TO '1024ms';
SET
postgres=# SHOW tcp_keepalives_idle ;
tcp_keepalives_idle
---------------------
1
(1 row)
