PostgreSQL: Transaction rollback rates
Rollback counts rise but user-visible errors remain unclear. Compare commits and rollbacks with application error categories and transaction volume.
Environment and inputs: PostgreSQL 18 documentation baseline; views, extensions and permissions vary across versions and managed services.
Failure scenario
Rollback counts rise but user-visible errors remain unclear. Confirm the cause before choosing a fix.
Evidence to collect
Compare commits and rollbacks with application error categories and transaction volume. Record the time, affected scope and a healthy comparison interval.
Fix the confirmed cause
Investigate unexpected failures separately from deliberate application rollbacks. Write the expected result first. Change one relevant setting at a time.
Check the result and hand over
Repeat the check for transaction rollback rates using the same scope and a representative interval. Check that the symptom is resolved, expected records are present and downstream results are correct. If coverage, correctness or latency worsens, restore the recorded configuration through the agreed rollback process.
Scope and precautions
Prefer read-only access and limit queries to the relevant period or dataset. This example has not been tested on your systems. Test changes in an approved environment. Keep credentials and sensitive data out of shared evidence.
