## Description

The filter_having extension allows Dataset#filter, and, or and exclude to operate on the HAVING clause if the dataset already has a HAVING clause, which was the historical behavior before Sequel 4. It is only recommended to use this for backwards compatibility.

You can load this extension into specific datasets:

    ds = DB[:table]
    ds.extension(:filter_having)

Or you can load it into all of a database's datasets, which is probably the desired behavior if you are using this extension:

    DB.extension(:filter_having)
