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.
