/etc/zulip/zulip.conf claims that Zulip is running PostgreSQL

$UPGRADE_FROM, but the server is connected to a PostgreSQL running

version $DATA_IS_IN. Check the output from pg_lsclusters to verify

which clusters are running, and update /etc/zulip/zulip.conf to match.

In general, this results from manually upgrading PostgreSQL; you

should use this tool for all PostgreSQL upgrades.
