Building RESTful Web services with Go

pq, a pure PostgreSQL database driver for Go

In the previous chapters when we dealt with SQLite3, we used an external library called go-sqlite3. In the same way, a database driver library is available to bridge both Go and PostgreSQL. That library is called pq. We can install that library using the command:

go get github.com/lib/pq

After getting this library, we need to use it in a similar way to SQLite3. The API will be in line to the database/sql package of Go. In order to create a new table, we should initialize the DB. To create a new database, just type this command from the psql shell, as shown in the following command; it is a one-time thing:

CREATE DATABASE mydb;

Now, we will write a small code illustration that explains the usage ...
