Add a flag to gitlab-ctl pg-upgrade to just perform symlinking
Would it be possible to add a flag to the pg_upgrade command to just perform the symlinking task (or any other tasks that would be required for DBs that are external to GitLab)?
We are using AWS RDS for our Postgres Instance and will need to upgrade outside of GitLab's process. I believe we'll want to symlink the 9.6 binaries before we upgrade to ensure GitLab doesn't have any issues.
