Re: Restoring a database problem

I was hoping there was a command in psql that would do both, that is,
kick the exisiting connections and stop new ones.  It was being a bit
optimistic I think, but such a command would be really useful, IMHO.

Modifying pg_hba.conf, is a little complicated. The daemons are using
the db owner's credential and the backups are on a different server so I
still need to be able to connect to do the restore.

I guess I will need something like

local    mydb    all                reject
host    mydb    postgres    0.0.0.0/0    password
host    mydb    postgres    ::0/0        password
host    mydb    all      0.0.0.0/0    reject
host    mydb    all        ::0/0    reject

then systemctl reload postgresql-10

then from the server with the backup on it
pg_restore -h db-server -Upostgres -c -C -d mydb mydb-backup

Modifying pg_hba isnt going to kick the existing connections, so I will
need to do that either using psql and the commands in the article Rob
posted, (I think I have used that method somewhere already). or kill
them on the DB server
