Seed dictionary and consensus schema at postgres init

User description

Seed dictionary and consensus schema at postgres init

This should reduce a bit the complexity of the database setup, removing the need to apply database migration.
(Since the database migration needed to be applied after all indexer had seed the db but before the taskboard start using the db, now the db launch all seeded (with schema only) and so we only need to apply metadata for the frontend to work, but the taskboard does not need metadata)

PR Type

enhancement, configuration changes

---

Description

• Enhanced the database initialization script to seed schemas and tables for consensus and dictionary, reducing the need for migrations.
• Improved service dependency management in docker-compose.yml by adding health conditions.
• Simplified GraphQL schemas by removing unused entities, which streamlines the data model.
• Removed migration scripts related to unique constraints, as they are no longer needed with the new initialization approach.

PR Reviewer Guide 🔍

Here are some key observations to aid the review process:

⏱️ Estimated effort to review: 4 🔵🔵🔵🔵⚪

🧪 No relevant tests

🔒 No security concerns identified

⚡ Recommended focus areas for review Database Schema Changes The PR includes extensive changes to the database schema and initialization scripts. It's crucial to ensure that these changes do not disrupt existing data and functionalities, especially in production environments. Thorough testing and validation against current database states and expected new states are required to prevent data loss or corruption. Service Dependency Management Modifications in service dependency conditions in the docker-compose file need careful review to ensure that services start in the correct order without causing startup failures or delays in environments where this configuration is deployed. GraphQL Schema Simplification The removal of several entities from the GraphQL schema needs to be validated to ensure that it does not affect the existing queries and operations that depend on these entities. It's important to check if any frontend or other dependent services require updates due to these changes.

PR Code Suggestions ✨

Explore these optional code suggestions:

Category	Suggestion	Score
Typo	Correct the port mapping for HTTPS to match the intended configuration Correct the port mapping for HTTPS from "443:9944" to "443:9945" to align with the intended configuration as per the comment. docker-compose.yml [20] -- "443:9944" # Map external 443 to Caddy's 9945 for HTTPS +- "443:9945" # Map external 443 to Caddy's 9945 for HTTPS Suggestion importance[1-10]: 10 Why: This suggestion corrects a critical typo in port mapping that could lead to a misconfiguration of the HTTPS service, impacting the application's security and functionality.	10
Best practice	Enhance reliability and rollback capabilities by using transactions for schema operations Use explicit transactions or savepoints around schema creation and modification to ensure atomicity and rollback capabilities in case of errors. indexers/db/docker-entrypoint-initdb.d/init-db.sql [15-16] -CREATE SCHEMA consensus; +BEGIN; +CREATE SCHEMA IF NOT EXISTS consensus; ALTER SCHEMA consensus OWNER TO postgres; +COMMIT; Suggestion importance[1-10]: 8 Why: Using transactions for schema creation and modification ensures atomicity and provides rollback capabilities, which is crucial for maintaining database integrity in case of errors during schema setup.	8
	Prevent errors by ensuring schemas are only created if they do not already exist Add IF NOT EXISTS to the CREATE SCHEMA statements to prevent errors if the schema already exists. indexers/db/docker-entrypoint-initdb.d/init-db.sql [15] -CREATE SCHEMA consensus; +CREATE SCHEMA IF NOT EXISTS consensus; Suggestion importance[1-10]: 7 Why: Adding IF NOT EXISTS to schema creation is a best practice to avoid errors during script execution if the schema already exists, enhancing the robustness of the database setup process.	7
	Ensure the btree_gist extension is available in the public schema to prevent scope issues Ensure that the btree_gist extension is created in the public schema before using it in other schemas to avoid potential scope issues. indexers/db/docker-entrypoint-initdb.d/init-db.sql [21] +CREATE EXTENSION IF NOT EXISTS btree_gist; CREATE EXTENSION IF NOT EXISTS btree_gist WITH SCHEMA public; Suggestion importance[1-10]: 5 Why: The suggestion to ensure the btree_gist extension is created in the public schema is valid for preventing scope issues, but the existing code already handles this correctly by specifying the schema during creation.	5
