## What it is
lib/pq is a pure Go PostgreSQL driver for the standard database/sql package. It supports all maintained PostgreSQL versions and libpq-compatible DSN connection strings.

## Use cases
- connect to postgresql from go
- go database/sql postgres driver
- run sql queries against postgres in go
- use postgres url connection strings in go
- handle postgres errors in go

## When to choose
- you use database/sql and need a mature, widely imported PostgreSQL driver
- you want libpq-style DSN support and run-time parameters in connection strings

## When to avoid
- you need high performance or binary protocol features - pgx is generally recommended instead
- you need PostgreSQL-specific types outside database/sql's generic interface

## Facets
- artifact type: library
- maturity: stable
- function: database-driver, database
- domain: databases, backend, developer-tools
- platform: go, cross-platform
- tags: postgresql, database-sql, sql-driver, libpq
