Good post mortem, just some thoughts, would love to hear what others think. Shouldn't the app developers be in charge of deploying their code and making sure its working? It seems odd that they pass off a migration like this to a DBA to then go deploy randomly, or that they weren't around when it was happening to monitor it. Also, it seems like there should have been a script that can be run that encapsulates the required dependencies, namely, don't drop an index before building the new one maybe? This should at least minimize the amount of context needed in a ticket. Relying on fully correct context in tickets seems like it could be super error prone.
