Upsert has been added to SQLite3 v3.24.0.

Since this feature has been wanted for quite a longtime, I hope we can see it soon and prod ready for go-sqlite3.

Best regards.

Quick question: Did you do an manual update or did you used the provided upgrade tool?

[tuxlinuxien]

I did the upgrade manually and run the test to make sure it was compatible. I have found out the upgrade tool just after my pull request.
I have seen the upgrade tool does some changes, but since the manual update still work, I was thinking it was not important.

But you are right, let me use the upgrade tool and push again and sorry if I have messed up.

@gjrtimmer I see my error when I don't use the upgrade tool, it had messed up with the includes. my latest commit fix that.

Thank for your tip.

@tuxlinuxien The new upgrade tool merges the User Authentication Module into the main binding, currently requried because this has been included within the master.

@gjrtimmer I have closed this PR and created a new one ( #589 ). I have used the upgrade tool and fixed the TestUpsert.
