SYSTEM DOCUMENTATION & REQUIREMENTS

What problem does it solve?

This skill standardizes and optimizes PostgreSQL usage in Go applications, enabling safe, scalable data access patterns for dynamic data like market data in eve-o-provit.

Core Features & Use Cases

Connection pooling with pgxpool for efficient resource usage.
Repository pattern with domain models and explicit transaction boundaries.
Prepared statements, NULL handling, and migrations for robust data layer.
Use case: Build a backend service that ingests live market data and stores it reliably in PostgreSQL, while enabling easy testing and migrations.

Quick Start

Install dependencies and run the service with a configured DATABASE_URL, e.g., export DATABASE_URL='postgres://user:pass@localhost:5432/db?sslmode=disable' and start the app.

FAQPage Schema

How do I implement the repository pattern with pgxpool for PostgreSQL in Go?▼

To implement the repository pattern with pgxpool in Go, you standardize data access by defining domain models and managing PostgreSQL connections through a pooled connection interface. This approach ensures safe transaction boundaries and maintainable query logic.

What is the best way to handle PostgreSQL NULL values in Go applications?▼

Handling PostgreSQL NULL values in Go is achieved by using pointers in your domain models. This method safely maps nullable database columns to Go structs without requiring complex custom null types, preventing runtime panic errors during data unmarshaling.

How do I manage versioned PostgreSQL migrations in a Go backend service?▼

Managing versioned PostgreSQL migrations in a Go backend requires a migration-first development approach. This process applies sequential schema changes to the database, ensuring that dynamic transactional records and market data structures remain synchronized across deployments.

Does this PostgreSQL connection pooling approach work for high-throughput market data?▼

Yes, this PostgreSQL connection pooling approach works for high-throughput market data. By utilizing pgxpool, the system maintains efficient resource usage and prepared statements, enabling reliable ingestion of live dynamic data without exhausting database connections.

How do I set up explicit transaction boundaries in a Go PostgreSQL repository?▼

Setting up explicit transaction boundaries in a Go PostgreSQL repository involves starting a transaction from the pgxpool connection and passing it through repository methods. This ensures that multiple database operations succeed or fail together atomically.

Can I use prepared statements with pgxpool for reliable Go data access?▼

Yes, you can use prepared statements with pgxpool for reliable Go data access. The connection pool automatically manages prepared statements, optimizing query execution performance for repeated transactional records while maintaining robust data layer integrity.
