Maps PostgreSQL parser BNF grammar statements to their corresponding PostgreSQL C source code entry points (e.g., in utility.c). Use this to find which C function handles a specific parsed SQL statement.

Synthesizes the outputs of pg-bnf-source-mapper, pg-write-trace-skill, and pg-read-trace-skill into a master PG_SEMANTIC_INVENTORY.json. It maps statements to regression tests (pg_regress) to provide a complete coverage plan.

Traces the PostgreSQL Analyzer (analyze.go/analyze.c) to identify which system catalogs (e.g., pg_operator, pg_type, pg_proc) are queried to resolve a specific SQL statement or semantic element. Use this to identify dependencies.

Traces PostgreSQL C source code to identify which system catalogs (e.g., pg_class, pg_attribute) are modified (inserted, updated, or deleted) by a specific handler function. Use this to find the side-effects of a DDL statement.

Use when given a GitHub issue URL or number to investigate and implement a fix. Triggers on "fix issue", "fix bug", "fix

Run and troubleshoot tests for DBHub, including unit tests, integration tests with Testcontainers, and database-specific tests. Use when asked to run tests, fix test failures, debug integration tests, troubleshoot Docker/database container issues, or add new tests. Also use when verifying code changes work correctly or when CI test failures need investigation.

Guide for querying databases through DBHub MCP server. Use this skill whenever you need to explore database schemas, inspect tables, or run SQL queries via DBHub's MCP tools (search_objects, execute_sql). Activates on any database query task, schema exploration, data retrieval, or SQL execution through MCP — even if the user just says "check the database" or "find me some data." This skill ensures you follow the correct explore-first workflow instead of guessing table structures.
