To connect to PostgreSQL, you can use either a DSN or an ODBC connection string. Both of these methods use the sql package's Open function.

Connect to a DSN

To connect using a DSN:

db, _ := sql.Open("odbc", "DSN=CData PostgreSQL Sys;")
defer db.Close()

Provide a Driver Connection String

To connect using an ODBC connection string:

db, _ := sql.Open("odbc", "DRIVER={CData ODBC Driver for PostgreSQL};User=postgres;Password=admin;Database=postgres;Server=127.0.0.1;Port=5432;")
defer db.Close()
