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 which may offer better performance in some applications.
