65.2. Built-in Operator Classes

The core PostgreSQL distribution includes the SP-GiST operator classes shown in Table 63.1.

Table 63.1. Built-in SP-GiST Operator Classes

Name	Indexed Data Type	Indexable Operators
kd_point_ops	point	<< <@ <^ >> >^ ~=
quad_point_ops	point	<< <@ <^ >> >^ ~=
range_ops	any range type	&& &< &> `-	-`<< <@ = >> @>
box_ops	box	<< &< && &> >> ~= @> <@ `&<	``<<		>> ``	&>`
text_ops	text	< <= = > >= ~<=~ ~<~ ~>=~ ~>~
inet_ops	inet, cidr	&& >> >>= > >= <> << <<= < <= =

Of the two operator classes for type point, quad_point_ops is the default. kd_point_ops supports the same operators but uses a different index data structure which may offer better performance in some applications.
