    How to update the Go version

System: Debian/Ubuntu/Fedora. Might work for others as well.
1. Uninstall the exisiting version

As mentioned here, to update a go version you will first need to uninstall the original version.
To uninstall, delete the /usr/local/go directory by:

  
## go-postgres-error-code
// Get error code
pqErr := err.(*pq.Error)
log.Println(pqErr.Code)


// Check error message
if err, ok := err.(*pq.Error); ok {
    fmt.Println("pq error:", err.Code.Name())
}
