PostgreSQL Skill
Expert assistance for PostgreSQL database design and optimization.
Capabilities
- Design optimal schemas
- Create performant indexes
- Implement full-text search
- Work with JSONB data
- Optimize query performance
- Configure replication
Indexing Patterns
-- B-tree for equality and range
CREATE INDEX idx_users_email ON users(email);
-- GIN for JSONB and arrays
CREATE INDEX idx_posts_tags ON posts USING GIN(tags);
-- Full-text search
CREATE INDEX idx_posts_search ON posts USING GIN(to_tsvector('english', title || ' ' || content));
-- Partial index
CREATE INDEX idx_active_users ON users(created_at) WHERE active = true;
JSONB Operations
-- Query JSONB
SELECT * FROM users WHERE metadata->>'role' = 'admin';
-- Update JSONB
UPDATE users SET metadata = metadata || '{"verified": true}'::jsonb WHERE id = 1;
