SYSTEM DOCUMENTATION & REQUIREMENTS

💡 This Skill requires psql, supabase, and includes scripts (resource) and references (resource) components.

What problem does it solve?

This Skill makes it easy to design, validate, and defend production-grade Supabase schemas for multi-tenant real estate and fintech workloads without sacrificing RLS safeguards, audit trails, or migration safety.

Core Features & Use Cases

  • Architectural Playbook: Guidance on choosing between Edge Functions, database functions, and PostgREST, selecting shared-schema vs schema-per-tenant, designing tenant_id-enriched tables, and configuring connection pooling strategies.
  • Compliance & Fintech Patterns: Enforces NUMERIC currency columns, audit trail shadow tables, idempotent payments, temporal tables, double-entry accounting, and retention guardrails that every finance-heavy workflow demands.
  • Production QA Signoff: Bundled db-qa-gate script plus reference docs to verify RLS coverage, tenant_id columns, indexes, migration naming, and function security before rolling out changes.
  • Use Case: Onboard a new tenant-focused leasing or payment product by having the architect evaluate schema design, migrations, RLS policies, and QA gate findings to avoid data leaks and performance regressions.

Quick Start

Ask it to review your Supabase schema, RLS policies, migrations, and QA gate findings for tenant isolation and fintech readiness.

Frequently Asked Questions about supabase-db-architect

High-intent search queries and answers about installing and using this skill.

FAQPage Schema
How do I design a multi-tenant Supabase schema for fintech workloads?▼

Multi-tenant Supabase schema design for fintech requires shared-schema or schema-per-tenant strategies with tenant_id-enriched tables. You enforce NUMERIC currency columns, audit trail shadow tables, and double-entry accounting patterns to maintain data integrity and compliance while isolating tenant data.

What is the best way to implement row-level security policies for multi-tenant real estate databases?▼

Row-level security for multi-tenant real estate databases requires tenant-aware RLS policies applied to every table. You configure connection pooling strategies and verify RLS coverage using a QA gate script to validate tenant isolation, ensuring users only access records belonging to their specific tenant_id before production rollout.

How do I run reversible migrations safely in Supabase PostgreSQL?▼

Reversible migrations in Supabase PostgreSQL require proper migration naming conventions and rollback scripts. You validate migration safety using a bundled QA gate script that checks naming patterns, function security, and index coverage before deployment, ensuring schema changes can be safely rolled back if issues arise.

Can I automate RLS coverage checks before deploying Supabase schema changes?▼

Automating RLS coverage checks in Supabase uses a db-qa-gate script to verify tenant_id columns, RLS policies, indexes, and function security. You run this validation script to confirm production readiness, catching data leak risks and performance regressions before schema changes reach production environments.

Does Supabase support double-entry accounting and audit trail shadow tables for fintech compliance?▼

Supabase supports double-entry accounting and audit trail shadow tables through PostgreSQL schema design patterns. You implement NUMERIC money columns for precision, temporal tables for tracking changes, and retention guardrails to meet fintech compliance requirements while maintaining tenant isolation through RLS policies.

When should I choose Edge Functions versus database functions in Supabase multi-tenant architecture?▼

Choosing between Supabase Edge Functions and database functions depends on workload proximity to data and processing requirements. You evaluate whether logic needs real-time data access through PostgREST, runs better as database functions for transactional integrity, or requires Edge Functions for external API integration in multi-tenant setups.
