PostgreSQL (professional)
Skill text is English; answer in the user’s preferred language when rules or the conversation specify it.
Use official PostgreSQL documentation for version-specific behavior; this skill encodes design discipline, MVCC-aware operations, query and index patterns, and RLS correctness — not a replacement for the manual. Confirm server major (SELECT version();) when behavior differs across releases.
Boundary
postgresql-pro owns the PostgreSQL server product: DDL/DML design, policies, migrations, plans, locks, vacuum/replication semantics. sql-data-access-pro owns embedded SQLite and portable SQL habits. performance-tuning-pro owns cross-tier latency diagnosis when the DB is only one segment. deployment-pro owns when and how migrations run in pipelines.
