{"answer":"Recommended action: Either install build prerequisites (C compiler, python3-dev, libpq-dev; add /usr/lib/postgresql/X.Y/bin to PATH if pg_config is elsewhere) or switch to psycopg2-binary for dev/test (the project advises source builds for production and for library dependencies).\n\nOption: Install libpq dev files [evidence: official_recommended_action]\nApplies when: See record scope.\nSteps:\n1.
