Step-by-Step Guide
1 Install PostgreSQL
Install PostgreSQL using your package manager or the official repository for latest versions. Access it using the postgres system user.
Pro Tips:
- Use official repo for latest version
- psql is the command-line client
2 Create Databases and Roles
PostgreSQL uses roles instead of users. Create roles with CREATE ROLE and databases with CREATE DATABASE. Use pg_hba.conf for authentication.
Pro Tips:
- roles can be users or groups
- Use password authentication for apps
3 Configure Connections
Edit postgresql.conf to set listen_addresses and pg_hba.conf to control which hosts can connect with which authentication methods.
Pro Tips:
- Default only listens on localhost
- Use md5 or scram-sha-256 for passwords
4 Optimize Performance
Tune shared_buffers, work_mem, and effective_cache_size based on available RAM. Enable pg_stat_statements for query analysis.
Pro Tips:
- Set shared_buffers to 25% of RAM
- ANALYZE updates query planner statistics
