Melhores práticas de Postgres e Supabase — indexação, RLS performática, connection pooling, schema design, locking e diagnóstico com EXPLAIN. Use ao escrever queries SQL, criar migrations, desenhar schema, implementar políticas RLS, otimizar queries lentas ou investigar timeouts e problemas de conexão em projetos Supabase/Postgres.
Collected from public GitHub. Every version is saved exactly as it was and never changes. Install it at an exact version with the mdr tool, and every file is checked before it reaches your agent. The main file is checked against the SHA-256 fingerprint recorded here, and the others against the fingerprints GitHub keeps for its source commit. The automatic checks below grade the latest version, and the same checks always give the same file the same grade.
What the file says
# Supabase / Postgres Patterns Skill de banco de dados destilada do guia oficial supabase-postgres-best-practices (8 categorias priorizadas por impacto). Usada por **dev-data-engineer, sites-data** (schema, migrations, RLS) e **dev-bi** (queries analíticas), com **dev-qa/sites-qa** em review de migrations. Segue o protocolo de segurança da squad: snapshot → dry-run → apply → smoke-test. ## 1. Query Performance (CRITICAL) **1.1 — Index every column used in WHERE, JOIN, and ORDER BY of hot queries.** Missing indexes are the #1 cause of slow queries. ```sql -- ❌ seq scan on 1M rows SELECT * FROM orders WHERE customer_id = $1; -- ✅ CREATE INDEX idx_orders_customer_id ON orders (customer_id); ``` **1.2 — Composite indexes: equality columns first, then range/sort.** ```sql -- query: WHERE status = 'paid' AND created_at > now() - interval '30 days' CREATE INDEX idx_orders_status_created ON orders (status, created_at); ``` **1.3 — Partial indexes for skewed data** (e.g., only 2% of rows are `pending`): ```sql CREATE INDEX idx_orders_pending ON orders (created_at) WHERE status = 'pending'; ``` …

How to install
mdr add joaoguirunas/team-os/data-supabase-patterns@sha256:0812a7e79bc73808The line at the top of this page pins the label v1.0, which is what most people want. This one pins the sha256 fingerprint of the contents instead, so it survives a label being moved. Either way the exact version is written to mdr.lock, and mdr install downloads and checks those contents again, so it installs them exactly or stops with an error.
