[HACKERS] question on Postgres smart shutdown mode

[Bo Tian]

Hi All,

I have a question on PG smart shutdown mode.
When shutdown Postgres by issuing Smart Shutdown mode (SIGTERM) request, is 
there a way for client to be notified of this shutdown event? I tried 
PG_NOTIFY, but I cannot get any notification events when this happens. BTW, I 
am relative new to Postgres.

Thanks,
Bo
