Tests should timeout in a reasonable time if something is stuck. In particular this is important when testing deadlock conditions such as can occur with the copy protocol if both the client and the server are blocked writing until the other side does a read.
pgconn
Package pgconn is a low-level PostgreSQL database driver. It operates at nearly the same level as the C library libpq. It is primarily intended to serve as the foundation for higher level libraries such as https://github.com/jackc/pgx. Applications should handle normal queries with a higher level library and only use pgconn directly when required for low-level access to PostgreSQL functionality.
Example Usage
pgConn, err := pgconn.Connect(context.Background(), os.Getenv("DATABASE_URL"))
if err != nil {
log.Fatalln("pgconn failed to connect:", err)
}
defer pgConn.Close(context.Background())
result := pgConn.ExecParams(context.Background(), "SELECT email FROM users WHERE id=$1", [][]byte{[]byte("123")}, nil, nil, nil)
for result.NextRow() {
fmt.Println("User 123 has email:", string(result.Values()[0]))
}
_, err = result.Close()
if err != nil {
log.Fatalln("failed reading result:", err)
}
