## Historique du projet et usages

Dexter is an automatic index recommender for PostgreSQL that analyzes query sources and proposes indexes using HypoPG before optionally creating them.

### Historique du projet

The official tag history starts in 2017, and the changelog shows a steady 0.x series focused on safer index suggestions, more input sources, PostgreSQL compatibility, Docker and Linux packaging, and support for newer Ruby and PostgreSQL versions.

### Historique d'adoption

Dexter entered the PostgreSQL performance-tool niche as a command-line utility that can read pg_stat_statements, live activity, log files, SQL files, and stdin. Its README documents installation through RubyGems, Docker, Homebrew, and Linux packages.

### Modes d'utilisation

A typical run points Dexter at a database and a query source, such as `dexter -d dbname --pg-stat-statements`. By default it reports candidate indexes; creating indexes requires an explicit `--create` flag.

### Pourquoi les passionnés de paquets s'y intéressent

The package is notable because it bridges application-level package managers and database-server extension packaging: the CLI is easy to install, but useful operation also depends on HypoPG being present and enabled on the PostgreSQL server.

### Chronologie

- 2017: v0.1.0 appears in the official tag history.
- 2017: early releases add pg_stat_statements, psql-style connection options, CSV input, multicolumn indexes, and schema support.
- 2023: v0.5.0 adds normalized-query support and changes several input and HypoPG safety defaults.
- 2025: v0.6.0 adds Linux packages for Ubuntu 24.04 and Debian 12 while dropping older runtime support.

### Related projects

- Dexter is tightly related to PostgreSQL, pg_stat_statements, pg_stat_activity, server log analysis, pg_query, and the HypoPG extension for hypothetical indexes.
