Auto close idle connections for specific user (not by pg_cancel command)

[Emi]

Hello,

In psql, may I know is there a way/config that idle connections could be 
auto closed (but not by pg_cancel_backend command) for specific user(s) 
please?

For example,
select  usename, waiting, query_start  from pg_stat_activity
where usename like 'connUser1' and
           current_query='<IDLE>';

All connections from connUser1, if idle more than 1 day, psql auto close 
them.

Thanks a lot.
