Re: Is there a way to view active connections?

Thanks, that worked.
I didn't really want to disconnect anyone active, but I had no other choice.
At least the restart accomplished what I wanted!

I want to do a server restart, so I issued the command
pg-ctl -w restart -D /usr/local/pgsql/data

However, the shut down fails:
pg_ctl: server does not shut down.

Unfortunately, when I try to see who is connected with psql, I get
FATAL: the database system is shutting down.

Is there any other way to see who is still connected?

Try using the option "-m fast" to either the shutdown or restart command to pg_ctl

pg-ctl -w restart -D /usr/local/pgsql/data -m fast

This disconnects any sessions currently connected. Thankfully in 9.5, this has become the default shutdown mode. Prior to 9.5, "-m smart" was the default which waits for all active connections to disconnect themselves.
