## What it is
Postgrex is a PostgreSQL driver for Elixir that communicates using PostgreSQL's binary protocol. It provides automatic encoding/decoding of Elixir values, extensible type support, and transactions and pooling via DBConnection.

## Use cases
- connect to postgres from elixir
- run raw sql queries in elixir
- query postgresql without an orm
- encode and decode postgres types in elixir
- use postgres transactions with connection pooling
- extend postgres type encoding for custom types

## When to choose
- you need direct, low-level PostgreSQL access from Elixir
- you want to use Ecto, which builds on Postgrex
- you need custom PostgreSQL type encoding/decoding

## When to avoid
- you want a high-level ORM with migrations and associations (use Ecto instead)
- you are not working with PostgreSQL

## Facets
- artifact type: library
- maturity: stable
- function: database-driver, database
- domain: databases, backend
- platform: elixir
- tags: postgresql, elixir, driver, dbconnection
