63.2. 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 that may offer better performance in some applications.
