Cannot read property 'COLUMN_NAME' of undefined

When calling columnInfo with a table and column name, if the search query returns undefined the function throws Cannot read property 'COLUMN_NAME' of undefined when mapping the response to Column.

This can be easily fixed, but it feels like we should consider what return type we want in this scenario. Personally I think columnInfo should return Column | undefined in this instance, but this would be a breaking change.

Should we return null/undefined, or throw an error that the table/column name is invalid? In the last case, it wouldn't be a breaking change

I personally feel like this function should return undefined, which lines up more with how other knex functions operate. But I also don't think it's worth doing a major increment just to make things a bit nicer! So probably best to just throw an error for now.
