My project's DB has a mutli-step stored procedure using Transaction Control that may take 30 minutes or more to complete.
I am curious if there is a way to make it more smart shutdown friendly so it can stop between steps?

We are using both PG 14 and PG 16 on Rhel 8.
Pardon me if it's obvious but is there a function to call or a table that could be checked after a commit within the procedure to determine a shutdown is pending?

Maybe somehow checking the log for a message like :

received smart shutdown request

Or use tail_n_mail against the log and then implement some logic using NOTIFY , ideally you want your procedure to be interrupted rather than do polling.


Thanks,
Dennis
