37-37: LGTM! Please add documentation for the new feature flag.The addition of
enableIndexTuningparameter follows good practices. However, documentation should be added to explain:
- The purpose and benefits of index tuning
- The relationship with
enableQueryPerformanceInsight- Any performance implications or recommended usage
Would you like me to help create a documentation PR for this feature?

- The purpose of the
enableIndexTuningparameter- The implications of enabling/disabling it
- Any prerequisites or dependencies
- Performance impact considerations
Example documentation:
param postgresConfiguration = { sku: { name: 'Standard_D4ads_v5' tier: 'GeneralPurpose' } enableQueryPerformanceInsight: false + // Controls automatic index tuning for PostgreSQL + // When enabled, the database automatically creates and removes indexes based on workload patterns + // Note: Requires careful monitoring in production environments enableIndexTuning: false }.azure/infrastructure/yt01.bicepparam (1)
37-37: Document index tuning implications.Consider adding documentation about:
- Performance implications during index tuning
- Monitoring recommendations

37-37: Verify if index tuning should be disabled in staging environment.
The default value is set to false in staging. While this is a conservative approach, please verify if this aligns with the testing strategy for this feature.
Let's check the configuration across other environments:
✅ Verification successful
Index tuning configuration appears to be intentionally disabled in production-like environments
Based on the configuration across different environments:
- Production, staging, and test environments have
enableIndexTuning: false - Only the yt01 (likely a development/sandbox environment) has
enableIndexTuning: true
This consistent pattern across production-like environments suggests that disabling index tuning in staging is intentional and aligns with the overall configuration strategy.

37-37: LGTM! Parameter follows existing patterns
The addition of enableIndexTuning parameter follows the existing configuration pattern and is appropriately placed alongside similar feature flags.
37-38: Verify configuration consistency across environments
Let's verify that the index tuning configuration is consistently defined across all environments, with special attention to the YT environment where it should be enabled.
✅ Verification successful
Index tuning configuration is correctly set across environments
The verification confirms that:
- Index tuning is disabled (false) in prod, staging, and test environments
- Index tuning is enabled (true) in the YT01 environment as expected
- The configuration is consistently defined across all environments

38-38: Verify if index tuning should be disabled in production
While it's prudent to be conservative with production settings, please confirm if disabling index tuning in production is intentional. Index tuning can significantly improve query performance by automatically adjusting indexes based on workload patterns.
Let's check the configuration across other environments:
✅ Verification successful
Index tuning configuration appears to be intentionally managed across environments
The configuration shows a clear pattern:
- YT01 (development):
enableIndexTuning: true - Test:
enableIndexTuning: false - Staging:
enableIndexTuning: false - Production:
enableIndexTuning: false
This consistent progression from enabled in development (YT01) to disabled in higher environments (test, staging, prod) suggests an intentional configuration strategy, likely to prevent automatic index changes from impacting production workloads without explicit approval.

37-37: Verify environment selection for initial index tuning enablement.
The change enables index tuning in YT01 while keeping it disabled in other environments, which is a good cautious approach. However, please verify that YT01 is the most appropriate environment for initial testing of this feature.
✅ Verification successful
Let me check the documentation files to better understand the environment hierarchy and purpose.
Based on the gathered information, I can now generate the final response:
YT01 is an appropriate environment for initial index tuning enablement
The configuration follows the team's established pattern for rolling out features:
- YT01 has index tuning enabled while prod/staging/test have it disabled, which aligns with the cautious deployment approach documented in the Configuration.md
- The environment hierarchy shows this is a proper testing environment before wider rollout
- The parameter is properly defined in the main.bicep and consistently applied across all environment files

147-155: Verify dependency requirement
The resource currently depends on pgms_wait_sampling_query_capture_mode, but index tuning might work independently of query performance insights. Consider if this dependency is necessary.
Consider parameterizing the tuning mode
The index tuning mode is hardcoded to 'report'. Consider making it configurable through a parameter to support different modes in the future without template changes.

+ 'off'

209-211: LGTM! Parameter correctly passed to PostgreSQL module.
The new enableIndexTuning parameter is properly passed to the PostgreSQL module, maintaining consistency with the existing pattern used for enableQueryPerformanceInsight.
