I'm not sure what uses postgresql.
during upgrade think there was a message about pg_upgradecluster or I
may have read that in manpage.
:~# ps -ef | grep postgre
postgres 599 1 0 09:36 ? 00:00:00
/usr/lib/postgresql/10/bin/postgres -D /var/lib/postgresql/10/main -c
postgres 600 1 0 09:36 ? 00:00:00
/usr/lib/postgresql/11/bin/postgres -D /var/lib/postgresql/11/main -c
shows postgresql-10 and -11 both running after reboot ( I thought
might dump 10 if not needed )
should I do "pg_upgradecluster" ?
how to find out if 10 is needed and if not needed stop it ?
please bear in mind I don't know what I'm doing.
I think that you should the following:
- drop existing cluster of PostgreSQL 11
- upgrade existing PostgreSQL 10 cluster to 11
- drop existing PostgreSQL 10
- remove PostgreSQL 10 packages
You have to use commands:
Why do I get the feeling I'm going to break something ?
with "pg_ctlcluster" assume cluster-version is "11" and action is "stop"
but how to find out what is this "cluster-name" for pg_ctlcluster,
pg_dropcluster and pg_upgradecluster ?
"pg_dropcluster [--stop] cluster-version cluster-name"
"pg_upgradecluster oldversion name [newdatadir]" ?
