Creating Bug Reports for Oracle-to-PostgreSQL Migration
When to Use
- Documenting a defect caused by behavioral differences between Oracle and PostgreSQL
- Writing or reviewing a bug report for an Oracle-to-PostgreSQL migration project
Bug Report Format
Use the template in references/BUG-REPORT-TEMPLATE.md. Each report must include:
- Status: ✅ RESOLVED, ⛔ UNRESOLVED, or ⏳ IN PROGRESS
- Component: Affected endpoint, repository, or stored procedure
- Test: Related automated test names
- Severity: Low / Medium / High / Critical — based on impact scope
- Problem: Expected Oracle behavior vs. observed PostgreSQL behavior
- Scenario: Ordered reproduction steps with seed data, operation, expected result, and actual result
- Root Cause: The specific Oracle/PostgreSQL behavioral difference causing the defect
- Solution: Changes made or required, with explicit file paths
- Validation: Steps to confirm the fix on both databases
Oracle-to-PostgreSQL Guidance
- Oracle is the source of truth — frame expected behavior from the Oracle baseline
- Call out data layer nuances explicitly: empty string vs. NULL, type coercion strictness, collation, sequence values, time zones, padding, constraints
- Client code changes should be avoided unless required for correct behavior; when proposed, document and justify them clearly
Writing Style
- Plain language, short sentences, clear next actions
- Present or past tense consistently
- Bullets and numbered lists for steps and validations
- Minimal SQL excerpts and logs as evidence; omit sensitive data and keep snippets reproducible
- Stick to existing runtime/language versions; avoid speculative fixes
Filename Convention
Save bug reports as BUG_REPORT_<DescriptiveSlug>.md where <DescriptiveSlug> is a short PascalCase identifier (e.g., EmptyStringNullHandling, RefCursorUnwrapFailure).
