How does this skill improve PostgreSQL performance?

It provides Claude with specialized indexing strategies, query patterns like cursor pagination, and scripts to detect table bloat or missing foreign key indexes.

Is this skill specific to Supabase users?

While it is based on Supabase best practices, the patterns and optimization techniques apply to any standard PostgreSQL environment.

Does it support modern PostgreSQL features?

Absolutely. It covers JSONB indexing with GIN, time-series data handling with BRIN, and concurrent job processing with SKIP LOCKED.

Can it help with database security?

Yes, it includes specific patterns for Row Level Security (RLS), secure schema defaults, and optimized policy writing to prevent data leaks.
