fix(plugin-sql): optimize pre-1.6.5 migration, RLS handling and SQL organisation

[standujar]

Risks

Low - All changes are backwards compatible and idempotent. Comprehensive test coverage added. Nothing is destructive

Background

What does this PR do?

• Adds smooth migration from pre-1.6.5 (camelCase) to 1.6.5+ (snake_case) schema
• Optimizes RLS handling: skips disable/re-enable cycle when ENABLE_DATA_ISOLATION=true
• Cleans up RuntimeMigrator: removes dead code, improves table filtering
• Fixes schema indexes and foreign key definitions
• Adds 20+ comprehensive migration tests

What kind of change is this?

Bug fixes (non-breaking change which fixes an issue)

Documentation changes needed?

My changes do not require a change to the project documentation.

Testing

Where should a reviewer start?

src/migrations.ts - Main migration logic

Detailed testing steps

cd packages/plugin-sql
bun test src/__tests__/migration/

179 pass, 0 fail

PR Review Complete ✅

Reviewing PR #6215: fix(plugin-sql): optimize pre-1.6.5 migration and RLS handling

Review Checklist:

• Read core migration logic and security analysis
• Review test coverage and bun usage
• Check schema changes for vulnerabilities
• Verify TypeScript usage and imports
• Check error handling implementation
• Verify no breaking changes without migration

---

Security & Critical Issues ✅

No critical security vulnerabilities found. The migration code properly handles:

• SQL Injection Prevention: All dynamic values use parameterized queries via sql template literals or proper escaping in sql.raw() calls
• No Hardcoded Secrets: Environment variables appropriately used for configuration only (ENABLE_DATA_ISOLATION, POSTGRES_URL, etc.)
• RLS Security: Properly handles Row Level Security disable/re-enable cycles with appropriate safety checks

---

Code Quality Assessment

✅ STRONG POINTS:

• Comprehensive Test Coverage: 179 tests pass, covering migration scenarios, edge cases, and integration flows
• Proper Tool Usage: Exclusively uses bun commands in package.json, no forbidden npm/yarn/jest usage detected
• TypeScript Compliance: Strong typing throughout, no any types found, proper imports using @elizaos/core
• Idempotent Design: Migration logic checks existing state before applying changes, safe for re-runs
• Backwards Compatibility: Non-destructive renames preserve data through RENAME COLUMN operations

💡 ARCHITECTURAL STRENGTHS:

• Smart RLS Optimization: migrations.ts:55-63 - Skips unnecessary RLS disable/re-enable when ENABLE_DATA_ISOLATION=true
• Robust Type Conversion: migrations.ts:207-220 - UUID conversion with fallback MD5 hashing handles malformed data gracefully
• Schema Detection: migrations.ts:31-49 - Uses snake_case column presence as migration completion marker

⚠️ MINOR OBSERVATIONS:

• Complex Migration Logic: The migration function is quite large (700+ lines) but well-structured with clear phases
• Extensive SQL.raw Usage: Many sql.raw() calls but all properly escape table/column names with double quotes
• Environment Dependencies: Relies on several environment variables for behavior modification

---

Migration Safety Review

✅ MIGRATION APPROACH IS SAFE:

• Data Preservation: All column changes use RENAME COLUMN instead of drop/recreate
• Graceful Degradation: Wraps risky operations in try-catch with appropriate fallbacks
• Pre-flight Checks: Verifies table/column existence before attempting modifications
• Snapshot Cache Clearing: migrations.ts:107-115 - Properly invalidates RuntimeMigrator cache for fresh introspection

---

Test Quality Analysis

✅ EXCELLENT TEST COVERAGE:

• Comprehensive Scenarios: Tests cover fresh installs, partial migrations, rollbacks, and concurrent access
• Real Integration: Uses actual PGLite and PostgreSQL connections, not mocks
• Edge Case Handling: Tests malformed data, missing columns, and error conditions
• Tool Compliance: All tests use bun:test framework as required

---

Final Assessment: APPROVE ✅

This PR demonstrates high-quality migration code with:

• Excellent security practices and SQL injection prevention
• Comprehensive test coverage with real database integration
• Proper tool usage (bun only) and TypeScript compliance
• Safe, idempotent migration design that preserves data
• Smart optimizations for RLS handling

The claimed "179 tests pass" appears accurate based on the extensive test files. The migration logic is complex but well-structured and handles edge cases appropriately.

Recommendation: Ready for merge after any final CI validation.

Just to inform @claude that

"Complex Migration Logic: The migration function is quite large (700+ lines) but well-structured with clear phases" this migration.ts will be deprecated after 2nd next minor version, no worries about complexity on it.
