I understand that there are times with critical issues and outages when DBA are to work until all is fixed, which may take up to 20 hours.

But if things are stable and settled, out of a standard 8-9-hour work day, how many hours are actually needed to finish daily routine work?

pg-safeupdate is a PostgreSQL extension designed to prevent users from accidentally updating or deleting too many records in a single statement by requiring a "where" clause in all update and delete statements.
