psql — PostgreSQL's interactive terminal client and SQL script runner. Use when connecting to or inspecting a Postgres DB from a terminal, running SQL scripts or one-off queries in shells/CI/agents (`-c`/`-f`/`-qAtX`/`--csv`), using meta-commands (the `\d` family, `\copy`, `\watch`, `\gexec`, `\if` scripting, `\pset`/`\x`, variables), `.psqlrc`, or fixing connection/auth issues. Includes `(pgNN+)` annotations. The psql client only — SQL syntax -> postgres-sql, server admin -> postgres-admin.

Database-engineering team — agents (schema-architect, query-performance-engineer, migration-engineer, db-reliability-engineer) for the OPERATIONAL/transactional data layer (OLTP): relational schema design and normalization (and when to denormalize), indexing strategy and query/EXPLAIN-plan tuning, safe zero-downtime schema migrations (expand/contract), and connection-pooling, transactions/isolation, replication, and backup/restore reliability. Postgres-leaning, principles portable to MySQL/SQL Server; NoSQL access-pattern guidance where it fits. skills, a decision-tree knowledge bank (index-choice + migration-safety trees + a dated 2026 capability map), best-practices, templates, commands, an advisory hook. Distinct from data-platform (analytics/ELT/warehouse) and analytics-engineering (dbt). Seams: ELT/warehouse -> data-platform, ORM/app data-access -> backend-engineering, managed DB infra -> cloud plugins. Requires ravenclaude-core@>=0.7.0.

Relational databases in one plugin: the engine-agnostic sql-best-practices skill (sargable predicates, joins, indexes, NULL logic, transactions, keyset pagination, safe migrations, parameterization), the mariadb-best-practices dialect skill (10.6+ divergences, RETURNING, sequences, system-versioned tables, Galera) that the code-review fan-in loads only when the detected engine is MariaDB, a database-engineer worker that applies schema, migration, indexing and pooling work, and a PreToolUse guard that asks before a destructive statement (DROP/TRUNCATE/unqualified DELETE-UPDATE) lands.
