Tried an upgrade to 11.1 today, both upgrading from 10 in a VM and a destroy/up to install with only 11. Both seemed fine, so I think this should probably be good to go ahead with. Some notes about the process for when I do the upgrade on the production server:
install postgresql 11sudo systemctl stop postgresql@10-main.servicesudo systemctl stop postgresql@11-main.servicesudo -u postgres /usr/lib/postgresql/11/bin/pg_upgrade --check -b /usr/lib/postgresql/10/bin -B /usr/lib/postgresql/11/bin -d /var/lib/postgresql/10/main/ -D /var/lib/postgresql/11/main/ -o '-c config_file=/etc/postgresql/10/main/postgresql.conf' -O '-c config_file=/etc/postgresql/11/main/postgresql.conf'edit /etc/postgresql/11/main/postgresql.conf to set port to 5432start postgresql 11restart pgbouncer---Optimizer statistics are not transferred by pg_upgrade so,once you start the new server, consider running: ./analyze_new_cluster.shRunning this script will delete the old cluster's data files: ./delete_old_cluster.sh
