## What it is
postgresqltuner.pl is a Perl script that analyzes a running PostgreSQL instance's configuration and produces a report with tuning hints, inspired by mysqltuner.pl. It inspects OS settings, memory configuration, connections, extensions, and version info to recommend configuration improvements.

## Use cases
- tune postgresql configuration for my server
- analyze postgres memory settings like shared_buffers and work_mem
- audit postgresql instance for misconfigurations
- get tuning advice for a postgres database
- check if my postgres settings use RAM efficiently
- run a health report on my postgresql instance over ssh

## When to choose
- you run self-hosted PostgreSQL and want quick config recommendations without installing agents
- you want a mysqltuner-style one-shot report for PostgreSQL
- you need to inspect remote instances via SSH or Docker

## When to avoid
- you need continuous monitoring and alerting rather than point-in-time analysis
- you use a managed cloud database without superuser access
- you want automated config changes rather than advice

## Facets
- artifact type: cli-tool
- maturity: active
- function: monitoring, developer-tools, database
- domain: databases, performance
- platform: cli, self-hosted
- tags: postgresql, tuning, perl, database-configuration, mysqltuner-inspired, devops, linux, docker
