$npx mdskill add github/awesome-copilot/creating-oracle-to-postgres-migration-bug-report

Generate structured bug reports detailing behavioral discrepancies found during Oracle to PostgreSQL data migration.

  • Documents defects arising from differing database behaviors between Oracle and PostgreSQL.
  • Requires knowledge of migration context and adherence to a specific bug report template.
  • Structures findings by detailing severity, root cause, and necessary remediation steps.
  • Outputs a comprehensive, actionable bug report ready for tracking and resolution.

# 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](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`).
