# What this PR does - `AlertGroupPostMortem` has no references in the codebase.. I stumbled across it while working on https://github.com/grafana/oncall/pull/5224 and decided to just remove it - Removing old Slack channel related `VARCHAR` columns; these were refactored to foreign key references to `slack_slackchannel` table in following PRs: - https://github.com/grafana/oncall/pull/5224 - https://github.com/grafana/oncall/pull/5199 - https://github.com/grafana/oncall/pull/5191 ## Checklist - [x] Unit, integration, and e2e (if applicable) tests updated - [x] Documentation added (or `pr:no public docs` PR label added if not required) - [x] Added the relevant release notes label (see labels prefixed w/ `release:`). These labels dictate how your PR will show up in the autogenerated release notes. |
