PostgreSQL in Production
PostgreSQL is a powerful open-source relational database known for reliability, extensibility, and standards compliance. Running it in production means mastering indexing, query planning, replication, transactions, and backup strategies.
The recipes in this collection cover schema design, query optimization, partitioning, replication, connection pooling, and migration patterns. Each guide connects database theory to operational practice.
