Db doc updates
Created by: DaedalusG
This PR attempts to pull in more info from a recent upgrade failure and provide some explanation to those users less familiar with psql
and sql
commands. This still feels like a draft, reviewers please suggest comments on areas to expand or retract information.
Main changes:
- integrated ending bullets into resolution steps, breaking steps into a tldr section and a detailed/explanation steps section
- included a little more information about non-frontend dbs, INDEX_CONCURRENTLY, how to deal with partially completed migrations, links to how to access database shells in various deployments
