Generally looks good, a few notes inline.

If it's not a lot of extra effort, it would be nice to have update be an interface{} to match the signature of the other database functions. Not a big deal if not.
| collection := current_session.DB(db.name).C(collection_name) | ||
|
|
||
| // Use mongodb set operator to update only the provided fields. | ||
| err := collection.Update(selector, bson.M{"$set": update}) |

It's my understanding that this will only merge top-level changes, not nested fields. If so, it might be worth noting this in the comment above.
ie
{
"foo": {
"bar1": 1,
}
}
merged with
{
"foo": {
"bar2": 2,
}
}
results in
{
"foo": {
"bar2": 2,
}
}
