Can you name popular libraries used for interacting with PostgreSQL database?

To work with PostgreSQL in Go, the following libraries are often used:

• database/sql together with the lib/pq driver — a standard approach for interacting with the database via the SQL interface.
• pgx — a more modern and performant driver and client for PostgreSQL, which can be used both with database/sql and independently.
• ORM libraries, such as GORM or Ent, which simplify database operations by providing an object-oriented interface.

Example of connecting using pgx:

import (
    "context"
    "github.com/jackc/pgx/v4"
    "log"
)

func main() {
    conn, err := pgx.Connect(context.Background(), "postgres://user:password@localhost:5432/dbname")
    if err != nil {
        log.Fatal(err)
    }
    defer conn.Close(context.Background())

    var greeting string
    err = conn.QueryRow(context.Background(), "select 'Hello, PostgreSQL!' ").Scan(&greeting)
    if err != nil {
        log.Fatal(err)
    }
    log.Println(greeting)
}
