creating-oracle-to-postgres-migration-bug-report Creates structured bug reports for defects found during Oracle-to-PostgreSQL migration. Use when documenting behavioral differences between Oracle and PostgreSQL as actionable bug reports with severity, root cause, and remediation steps.

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).
