No description provided.

Tests are failing for a strange reason in some environments

I just realized this has already been done in #178, but I did not use the DEFAULT keyword. Maybe you can take a look here? If this is merged I intend to add more functions' missing variants.

Please merge master and see if that fixes things. Also, please see the test that's failing in #178; we need to ensure that the (table, column) and (table, column, description) variations continue to work without requiring casting.

Hey @nasbyj, I tried by just rebasing but it seems my PR has issues now. Maybe you can take a look at it. I have the Allow edits from maintainers enabled. I will add you to my repository where the branch is being updated so you can push there.

Is this something you'd still like to do, Jim?

Merged in 8f4a881, thank you!
