nit: t and s are not very descriptive variable names

It looks like some of these work with or without parens, while others require parens. We should have a test that current_timestamp() works and now doesn't.

FYI, I'm pretty sure you don't have to add all of these here and you don't have to add them to sql.ly either. The extract_arg rule accepts IDENT which will capture all of these strings.
