Run a shell script before killing the process

What's going wrong?

This is more a question than an issue.
I start an app with PM2 by running a shell script.
When I stop the process, I need to run a shell script before PM2 kills the first process.
How can I do that?
The reason for running a stop script is that in the start script we insert a row in the database, and we must remove the row in the database before stopping the process.

If I could get an example how to do this, I'll be incredibly happy.
If not, I would like to make this as a request that it should be possible to run something before killing the process.

How could we reproduce this issue?

Start an app a by running a shell script (bash).
Insert a row in the database in a table.

Stop the app by running a shell script.
Remove the row from the database before the process is killed.

No source file, test, or entry point is named. Start by tracing how PM2 handles stop signals and process termination, using the reported SIGINT and SIGTERM timeout behavior as context. Define the expected pre-stop hook behavior and verify that database cleanup can complete before the process is killed.
