Обсуждение: [ADMIN] Pg_upgradecluster failed

Hi all,

I try to upgrade from 9.3 to 9.5

ii  postgresql-9.3               9.3.14-1.pgdg70+1 amd64
object-relational SQL database, version 9.3 server
ii  postgresql-9.5               9.5.5-1.pgdg70+1 amd64
object-relational SQL database, version 9.5 server

But with my command I got this error :

oot@bas40:/etc/postgresql/9.3/main# pg_upgradecluster -v 9.5 -m upgrade
9.3 main
Disabling connections to the old cluster during upgrade...

I get this error on some of my pgsql servers and it's work on other one.
If I check the dataallowconn on my server :

Hi,

pg_upgradecluster relies on the template1 database being accessible
for maintenance operations during the upgrade. This is currently not
configurable, but we could certainly add an option to allow passing a
different database (e.g. "postgres") for the upgrade.

Uhm, "template0" must never be connected to, you shouldn't have set
datallowconn = 't. for it.

(It seems this was even wrong before you changed it now)
