The tables listing all the operator classes available for BRIN, GIN, GiST and SP-GiST had a confusing format where the same operator could be listed multiple times, for different data types. This improves the shape of these tables by adding the types associated to each operator, for their associated operator class. Each table included previously the data type that could be used for an operator class in an extra column. This is removed to reduce the width of the tables as this is now described within each operator. This also makes the tables fit better in the PDF documentation.
