buster upgraded postgresql
this last upgrade buster upgraded postgresql-10 to 11
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 reboot
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.
