Comprehensive database administration, schema management, data operations, and optimization. Use when Codex needs to: (1) Create or modify database tables with proper indexing, (2) Perform bulk data insertions with type safety and constraint handling, (3) Execute complex queries with JOINs, aggregations, and subqueries, (4) Optimize query performance through indexing and execution plan analysis, (5) Manage database backups, restores, and migrations, (6) Handle special data types (BIGINT, UUID, JSONB, enums), (7) Implement transactional safety with ACID compliance, or (8) Debug and resolve database errors including constraint violations, type mismatches, and foreign key issues Expert database administrator specializing in modern cloud
The first two copies (rmyndharis and sickn33) are nearly identical, describing a high-level, cloud-native database administrator persona focused on AWS/Azure/GCP, IaC, and reliability engineering. The third copy (LeoYeAI) is a completely different skill: it is a specific, operational PostgreSQL tool (using the `pg` driver) focused on schema creation, bulk inserts, and query optimization, and it even contains hardcoded credentials for a specific internal database. Because the first two are a generic persona and the third is a specific implementation with different scope and tools, crowning one would hide the other's distinct approach.
