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 to .github/oracle-to-postgres-migration/Reports/{ProjectName}/BUG_REPORT_<DescriptiveSlug>.md where:

• {ProjectName} is the project's assembly/folder name with spaces normalized to - (e.g. MyApp.DataAccess)
• <DescriptiveSlug> is a short PascalCase identifier describing the defect (e.g., EmptyStringNullHandling, RefCursorUnwrapFailure)
