1. Create a pg_hba_maintmode.conf with only the relevant hosts in it.
2. Copy pg_hba.conf to pg_hba_multi.conf.
3. Copy pg_hba_maintmode.conf to pg_hba.conf.
4. pg_ctl reload.
5. Use pg_stat_activity and pg_cancel_backend() to kill the application
connections.
6. Do your work.
7. Copy pg_hba_multi.conf to pg_hba.conf.
8. pg_ctl reload

Or... just shut down the user application.
