After upgrading a working installation on Ubuntu 14, we are getting 502 errors. Status shows that postgresql is not loading.
In the postgressql logs, we have:
FATAL: database files are incompatible with server
DETAIL: The data directory was initialized by PostgreSQL version 9.2, which is not compatible with this version 9.6.3.
Is there a way to upgrade the data within gitlab? Or do I need to upgrade the data to 9.6.3 separately using postgresql commands?
