62.2. Built-in Operator Classes
The core PostgreSQL distribution includes the SP-GiST operator classes shown in Table 62-1.
Table 62-1. 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 | < <= = > >= ~<=~ ~<~ ~>=~ ~>~ |
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.
